Item 20 You pay $4.35 for 0.75 pound of American cheese. You buy 2.5 pounds of Swiss cheese for $7.98 per pound. a. How much less does American cheese cost per pound than Swiss cheese? $ less per pound b. How much more do you spend on Swiss cheese than on American cheese? $
Answer:
a. $2.18
b. $15.60
Step-by-step explanation:
a. Price per pound of American cheese = $4.35 / 0.75 = $5.8
Price per pound of Swiss cheese = $7.98
Difference in price per pound = $7.98 - $5.8 = $2.18
b. Total amount spent on swiss cheese = $7.98 x 2.5 = $19.95
Amount spent more on Swiss cheese than on American cheese = $19,95 - $4.35 = $15.60

A music club membership costs $15 to start and $8 per cd. Write an equation.
Answer:
y = 8x + 15
Step-by-step explanation:
Let x represent the number of cds, and let y represent the total cost.
Since each cd is $8, we can represent the extra cost from cds with the term 8x.
And, since the membership costs $15, this cost can be represented in the equation by +15.
Put these together:
y = 8x + 15 will be the equation representing this

The radius of a circle with area A can be approximated using the formula r = the square root of A/3 . Estimate the radius of a wrestling mat circle with an area of 452 square feet. Round to the nearest integer.
Answer: 12
Step-by-step explanation:
Given:
A = 452
r = √A/3
Step 1: Substitute 452sqf for A
r = √452/3
Step 2: Solve
452 ÷ 3 = 150.66∞
√150.66∞ = 12.27∞
12.27∞ rounded to the nearest integer equal 12

Step-by-step explanation:
38+x+x+2=180
40+2x=180
2x=140
x=70
Answer:
70
Step-by-step explanation:
x +x +2 + 38 = 180 {Angle sum property of triangle}
2x + 40 = 180
2x = 180 - 40
2x = 140
x = 140/2

A community center rents their hall for special events. They charge a fixed fee of $200 plus an hourly fee of $22.50. Lin has $300 to spend on renting the hall for a fundraiser.
Using only the money she has, can Lin pay for a 6 hour event? Explain or show your reasoning.
Using only the money she has, can Lin pay for a 3 hour event? Explain or show your reasoning.
If LaTeX: hh represents the number of hours, what does LaTeX: 22.50h+20022.50 h + 200 represent?
Write and solve an equation to determine the number of hours Lin can rent the community center.
Write and solve an inequality that represents this situation. Explain what the solution to the inequality means in this situation.
Lin can only rent the hall for 4 hours with $300.
Linear equationLinear equation is in the form:
y = mx + b
where y,x are variables, m is the rate of change and b is the initial value of y.
Let c represent the cost of renting the hall for h hours.
From the question, we get:
c = 22.5h + 200
If Lin has $330, hence:
300 = 22.5h + 200
h = 4.4 hours
Therefore Lin can only rent the hall for 4 hours with $300.
