Another store, Healthy Pets, sells dog food in 50-pound bags for $92.13 per bag. If one bag of food from Pets Galore costs $48.15, how much would Seth save by buying 150 pounds of dog food from Pets Galore instead of from Healthy Pets?

$140.91

Step-by-step explanation:

50 pounds = 1 bag

150 pound bags = 150 ÷ 5

3 bags

Another store, Healthy Pets, sells dog food in 50-pound bags for $92.13 per bag.

1 bag = $92.13

3 bags = x

Cross Multiply

x = 3 × $92.13

$276.39

If one bag of food from Pets Galore costs $48.15

1 bag = $48.15

3 bags = x

x = 3 × $48.15

x = $135.48

The amount would Seth save by buying 150 pounds of dog food from Pets Galore instead of from Healthy Pets is

$276.39 - $135.48

= $140.91

Multiply 9 by 0.25 (make 25% into a decimal)
$9.00 x 0.25 = $2.25
So, you’d save $2.25

To go further...
Subtract that product from the original price and the answer to that is how much you’d get the cake for.
$9.00 - $2.25 = $6.75
