Lets say cookies = x and days = y.

2x times y = 15.

8x times y = 45.

Solution:

we are given that

Emma has 15 cookies and eats 2 cookies per day.

So the number of cookies left after n days can be written as

Emma=15-2n

Evan has 45 cookies and eats 8 each day.

So the number of cookies left after n days can be written as

Evan=45-8n

Number of days after which they will have equal number of cookies can be found as below

15-2n=45-8n

8n-2n=45-15

6n=30

n=5

Hence both will have equal number of cookies after 5 days.

grandymaker [24]
In each case divide the price by the number of cans.
The best buy is the lowest price.
$12.53/7 = $1.79
$5.97/3 = $1.99
$7.95/5 = $1.59
$8.34/6 = $1.39

The fourth ad, $8.34 for 6 cans results in the lowest price per can, $1.39.
The fourth ad is the best buy.
