Answer:
3
Step-by-step explanation:
6 bags of dog food × $9 = 54
$89 total - $54 spent on dog food = $35 spent on cat food
$35 / $8 = 4.375, but you can't have decimals for cat food bags so round down.
= 4 bags of cat food
2/5 multiply the top and bottom number by 20 you get 40/100 which is the same as 40%
