Rob sells electronics and earns $625 per week, plus 12% of his sales. Last week, he sold $3250 worth of electronics. What was his total earnings for last week?
Answer:
$1,015
Step-by-step explanation:
Given that:
Weekly earning = $625
Commission = 12% of sales
sales made last week = $3250
Last week earning = weekly earning + commision on sale
Commission on sale = 12% of sales
Commission on sale = (0.12 * 3250) = $390
Last week earning = weekly earning + commision on sale
Last week earning = $625 + $390 = $1,015

Students at Mendel Middle School are planning a fair for their school's fundraiser. Liam volunteers to help plan the event. The first month, he volunteered for x hours. The next month, he volunteered for 1 2/3 times as many hours as he had the first month. If he volunteered for a total of 40 hours, how many hours did he volunteer during the first month? Write an equation to represent the situation and solve.
Answer:
15 hours
Step-by-step explanation:
[tex]x[/tex] is the number of hours that Liam volunteered in the first month
The next month he volunteered [tex]1\dfrac{2}{3}[/tex] times the time he volunteered the first month.
Total time he volunteered in the two months is 40 hours so
[tex]x+1\dfrac{2}{3}x=40\\\Rightarrow x+\dfrac{5}{3}x=40\\\Rightarrow \dfrac{3x+5x}{3}=40\\\Rightarrow x=\dfrac{40\times 3}{8}\\\Rightarrow x=15[/tex]
Time he volunteered in the first month is 15 hours.

A local school donated canned goods to help the community. Cans were packed into boxes each weighing 16.4 pounds. The volunteers packed 9 boxes. How many total pounds of food did they collect? A. 97.6 B. 147.6 C. 976 D. 1,476
Answer:
147.6 pounds of foodStep-by-step explanation:
Each box weighed 16.4pounds, if the volunteers packed 9 boxes, we need to calculate the total pounds of food collected. Using the equality postulate;
1 box = 16.4 pounds
9 boxes = x pounds of food
Cross multiply;
1 * x = 9 * 16.4
x = 147.6 pounds of food
Hence the volunteers collected 147.6 total pounds of food

Eight bottles of soda and four bags of chips cost $16. Six bottles of soda and 7 bags of chips cost $14. How much does a bottle of soda cost? How much does a bag of chips cost?
Answer: soda 1.75 dollars and chips is 0.50 dollars
Step-by-step explanation:you have to work out the question like a simultaneous equation so key s=soda and c=chips
8s+4c=16
6s+7c=14 make chips equal
56s+28c=112
24s+28c=56 Take the equations away
32s=56
S=56\32
S=7/4
S=1.75 sub that answer in the first equation
8*1.75=14
14+4c=16
4c=2

What value of x satisfies the equation x/4 + x/2 =9
"12" is the correct value of "x" which satisfies the given equation.
The given equation is:
→ [tex]\frac{x}{4} +\frac{x}{2} =9[/tex]
By taking L.C.M, we get
→ [tex]\frac{x+2x}{4}= 9[/tex]
→ [tex]\frac{3x}{4} =9[/tex]
By applying cross-multiplication, we get
→ [tex]3x=36[/tex]
→ [tex]x = \frac{36}{3}[/tex]
→ [tex]= 12[/tex]
Thus the above is the right answer.
