Question

Ari thinks the perfect milkshake has 5 scoops of ice cream for every 3 spoonfuls of caramel. Freeze Zone makes batches of milkshakes with 10 scoops of ice cream and 7 spoonfuls of caramel.

What will Ari think about the amount of caramel in Freeze Zone's milkshakes?
A. Freeze Zone's milkshakes have too much caramel.
B. Freeze Zone's milkshakes have too little caramel.
C. Freeze Zone's milkshakes are just right.

Answer 1

Ari would think Freeze Zone's milkshakes have too much caramel, as Freeze Zone uses 7 spoonfuls of caramel for 10 scoops of ice cream, whereas Ari's ideal ratio would require only 6 spoonfuls.

Step-by-step explanation:

Ari believes the perfect milkshake ratio is 5 scoops of ice cream for every 3 spoonfuls of caramel. To determine what Ari would think about Freeze Zone's milkshakes, we need to compare this ideal ratio to Freeze Zone's ratio, which is 10 scoops of ice cream to 7 spoonfuls of caramel.

To compare the ratios, we can scale Ari's perfect ratio to the same amount of ice cream scoops in Freeze Zone's milkshake. If we double Ari's ice cream quantity from 5 to 10 scoops (multiplying by 2), we should do the same for the caramel spoonfuls to maintain the ratio, which then becomes 5 scoops x 2 = 10 scoops of ice cream and 3 spoonfuls x 2 = 6 spoonfuls of caramel. Freeze Zone uses 7 spoonfuls of caramel, which is one more spoonful than the 6 spoonfuls Ari prefers for 10 scoops of ice cream. Therefore, Ari will think Freeze Zone's milkshakes have too much caramel.
