Jeff sells popcorn for $3 per bag. To make a profit each day, he needs to sell at least $120 worth of popcorn. He has sold $36 worth of popcorn today. Which inequality can be used to find the number of bags of popcorn, p, Jeff still needs to sell today to make a profit?
Answers
Answer:
The inequality tha can be used to find how many more bags of popcorn Jeff still needs to sell today to make a profit is
x - 12 ≥ 40.
Step-by-step explanation:
Let us represent the number of bags of popcorn as p
Jeff sells popcorn for $3 per bag. To make a profit each day, he needs to sell at least $120 worth of popcorn.
We have the equation:
$3 × p ≥ $120
3p ≥ $120
p ≥ 120/3
p ≥ 40 bags
He must sell at least 40 bags to make a profit
He has sold $36 worth of popcorn today.
1 bag is $3
Hence, he has sold
$36/$3 = 12 bags of popcorn
Which inequality can be used to find Jeff still needs to sell today to make a profit?
This equality is given as:
x - 12 bags ≥ 40 bags
x - 12 ≥ 40
x ≥40 - 12
x ≥ 28 bags
She still need to sell 28 more bags of popcorn.
Jake plans to use a ramp to make it easier to move a piano out of the back of his truck. The back of the truck is 83 centimeters tall and the ramp is 158 centimeters long
Answers
Given :
Height of the ramp, h = 83 cm.
Length of ramp, L = 158 cm.
To Find :
Length of the base of the ramp.
Solution :
Let length of the base is l.
By Pythagoras theorem :
L² = h² + l²
[tex]l=\sqrt{L^2-h^2}\\\\l=\sqrt{158^2-83^2}\\\\l=134.44\ cm[/tex]
Therefore, length of the base is 134.44 cm.
Hence, this is the required solution.
At Best Buy, you buy a 55-inch TV for $499.99. You include the 2-year protection plan for $69.99. Tax in Indiana is 7%. How much tax will you pay? What is your final price?
Answers
Answer:
$609.8786
Step-by-step explanation:
Given that :
Cost of TV = $499.99
Protection plan = $69.99
Sales tax = 7%
Sales tax to pay :
Tax % * ( total cost of purchase)
0.07 * (499.99 + 69.99)
0.07 * 569.98
= $39.8986
Total price:
Cost of TV + cost of protection plan + sales tax
499.99 + 69.99 + 39.8986
= $609.8786

(13) The x and y intercept of the line x + y = 1 are 1 and 1 respectively.
(14) The x and y intercept of the line x + 2y = 6 are 6 and 3 respectively.
What is the slope intercept form of an equation ?When any equation is represented in the y = mx +c form, it is called the slope intercept from of the equation.
Here m is slope and c is constant.
(13)
The given equation of line,
x + y = 1
x intercept of the line is at y = 0,
x + 0 = 1
x = 1
y intercept of the line is at x = 0,
0 + y = 1
y = 1
The x and y intercept of the line x + y = 1 are 1 and 1 respectively.
(14)
The given equation of line,
x + 2y = 6
x intercept of the line is at y = 0,
x + 0 = 6
x = 6
y intercept of the line is at x = 0,
0 + 2y = 6
y = 3
The x and y intercept of the line x + 2y = 6 are 6 and 3 respectively.
