gtnhenbr [62]
Answer:

Ray = 19 yrs old
Tom = 25 yrs old
John = 57 yrs old

Explanation:

Let x be the years of Tom

R = x - 6
J = 3R = 3(x - 6)
T = x

R + J + T = 101
x - 6 + 3(x - 6) + x = 101
2x - 6 + 3x - 18 = 101
5x - 24 = 101
5x = 125
x = 125/5 = 25

R = 25 - 6 = 19
J = 3(25 - 6) = 57
T = 25

blondinia [14]
Answer:
Store 1 has the better deal.

Explanation:
If you divide the amount the prices by the amount of paper towel roll, you would see store 1 has the better deal.

3.60 divided by 12 = 0.30
3.50 divided by 10 = 0.35

As you can see, store 1 is less expensive than store 2. Therefore, store 1 is the better deal.
