Answer :
Answer: A sixty day supply of cat food for her two cats will cost her $125
Step-by-step explanation:
Carol has two cats Rover and Bobo.
Let x = the quantity of a can of fast food.
Rover eats three fourths of a can of cat food each day. This means that Rover eats 3x/4 each day. Bobo eats a half of a can of cat food each day. This means that bobo eats x/2 each day.
Cat food costs five dollars for three cans. This means that 3x = 5
Total number of cans consumed by both dogs in a day is 3x/4 + x/2 =5x/4
That means the cost per day would be
(5x/4 × 5)/3x = 25x/4 ×1/3x
= 25/12
It costs her $25/12 per day
To determine the cost for 60 days, we would multiply the cost per day by 60. It becomes
25/12 × 60 = $125
