If Jamie's age is represented as x and given that Ana is the same age as Jamie then, Ana's age can also be represented by x. The sum of their ages is equal to,
Sum of their ages = x + x
Simplifying,
Sum of their ages = 2x
Percent means parts out of 100
7%=7/100=0.07
'of' means multiply so
7%=0.7
7% of 280=0.07 times 280=196
12%=0.12
12% of 300=36
2%=0.02
2% of $1250=$25
It doesn't give the entire question, Do they want to know how many pieces were in the total cake? If so, I think it would be 384. You subtract the 3 pieces that Mindy ate and that leaves 96 that Tony had which was supposed to be 1/4 of the cake. Dividing the cake into 4 sections of 96 and multiplying would give you 384.
If they want to know how many slices of cake were left after Tony ate the fourth (96 slices), it would be 288
