One pet store charges $51 to groom a cat. Another pet store’s grooming costs in dollars, g, are modeled by the equation g=65.5c, where c is the number of cats. How much more would it cost to groom 3 cats at the more expensive store?

It would cost 43.5 dollars more to groom 3 cats at the more expensive store.

Step-by-step explanation:

Pet store #1: y= 51(3)= 153

Pet store#2: y=65.5(3)= 196.5

Difference: 196.5 - 153= $43.5

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

it is contrapositive
