One 40 pound bag of dog food will last rover 32 days. At that rate how many pounds of dog food does rover need in 60 days?

68

70

72

75

Rover will consume 75 lb of dog food in 60 days.

Step-by-step explanation:

The ratio 32 days to 60 days is equal to the ratio 40/x:

32/60 = 40/x

Cross multiplying, we get 32x = 60*40, or 32x = 2400

Then x = 2400/32 = 75

Rover will consume 75 lb of dog food in 60 days.

the answer is 75 pounds
