Answer:
$125
Step-by-step explanation:
Rover eats 3/4 of a can in a day ( so a quarter or 1/4 of a can is left)
Bobo eats 1/2 of a can in a day ( so a half or 1/2 of a can is left)
Together they eat 3/4 + 1/2 = 1/2 + 1/4+ 1/2 = 1 can and 1/4 in a day
( because 3/4 = 1/2+1/4 and 1/2 + 1/2 = 1 )
In 60 days together they eat
60 cans + (1/4 ) *60 = 60 + (60/4) = 60 + 15 = 75 cans in 60 days
3 cans costs $5
75 /3 = 25 packs with 3 cans in them
25 packs * $5 = $125 cost for 60 days supply
