The answer to Question 6 is

3) 150

Step-by-step explanation:

Calvin and Susie baked some cookies in the ratio 3:7 respectively.

Calvin Baked 60 cookies fewer than Susie.

Let us assume that

15×3 : 15×7

= 45:105.

i.e 105-45=60

Which means that Calvin and Susie baked 45 and 105 cookies respectively with Calvin having baked 60 cookies less than Susie.

The total cookies they both baked altogether are 45+105 = 150 cookies.
