Answer:
Bette needs 8 jumbo cans to frost 280 cupcakes
Explanation:
1 jumbo can is equivalent to 35 cupcakes, as we can see it takes 5 jumbo cans to get 175 and 3 to 105 the gap of 105 and 175 is 70 and the gap of 3 and 5 is 2 which means we divide 70 to 2 which the answer is 35, now we know its 35 we need to divide 280 and 35 now which the answer is 8.
