Question

Suppose 8x + 16 ice cream cones were sold on Saturday and 7x – 9 were sold on Sunday. What is the total number of ice cream cones sold? A. 15x + 25 B. 15x + 7 C. x + 7 D. x + 25

Answer 1

B. 15x + 7

Explanation:

We are given that,

The number of ice-creams sold on Saturday = 8x + 16 and

The number of ice-creams sold on Sunday = 7x - 9

Therefore,

The total number of ice-creams sold = Number of ice-creams sold on Saturday + Number of ice-creams sold on Sunday

i.e. Total number of ice-creams = (8x+16)+(7x-9) = (8x+7x)+(16-9) = 15x + 7

Hence, the total number of ice-creams sold is 15x + 7.

Answer 2

option:B

Explanation:

on saturday the number of ice-cream cones sold are 8x+16

on sunday the number of ice cream cones sold are 7x-9

so the total number of ice cream cones sold are=number of ice cream cones sold on saturday+number of ice cream cones sold on sunday

=8x +16+7x-9

=15x+ 7

hence option B is correct.
