2)
32/28=w/7
you cross multiply one denominator by the other numerator so
32(7)=(28)(w)
simplify
224=28w
divide 28 from both sides to get w alone
8=w

4)
36/21=24/s
cross multiply just like in the last problem
(36)(s)=(21)(24)
simplify
36s=504
divide 36 to get s alone and essentially solve for s
S=14

Alexus [3.1K]

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

Audrey has $111 to spend on a tennis racket and lessons. The racket costs $55 and the lessons cost $14 per hour. Define a variab
Mnenie [13.5K]

Answer:

Audrey can afford 4 hours of lesson.

Step-by-step explanation:

Given that:

Amount Audrey has to spend = $111

Cost of racket = $55

Cost per lesson = $14

Let,

y be the total cost

x be the number of hours

According to given statement;

y = 14x + 55

111 = 14x + 55

111 - 55 = 14x

14x = 56

Dividing both sides by 14

\frac{14x}{14}=\frac{56}{14}\\x=4

Hence,

Audrey can afford 4 hours of lesson.
