Using the following prices, calculate the unit price to determine how much it would cost for 7 granola bars and 9 bottles of water.
$7.14 for 6 granola bars

$8.72 for 8 bottles of water

a. $18.14

b. $18.63

c. $21.41

d. $31.72

$7.14 divided by 6 equals $1.19. That means the granola bars cost $1.19, so 7 granola bars would be $8.05. We then bring $8.05 down.

$8.05

$8.72 divided by 8 equals $1.09. That means 1 bottle of water cost $1.09, so 9 bottles of water would be $10.09.

$8.05 + $ 10.09 = $18.14
