Answer 1

11.2 Slices / Week

Explanation:

We know that Jake has eaten 5 slices of cake in 3 days. You can divide 5 / 3 to get an average of 1.6 slices of cake being eaten per day. The question asks what the weekly rate or eating the cake will be, do you need to multiple 1.6 x 7 for the total amount of cake eaten per week, which is 11.2 slices!

Answer 2

11.6

explanation

we have 7 days.

7days-3days =4

in 3 days he has eaten 5 slices

again 4-3 days=1

so in 6 days he has eaten 10 slices

we have 1 day left.so if he eats 5 slices in 3 day,how many he eat slices in 1 day?5/3=1.6

10+1.6=11.6
