Question

Three questions answer all of them for 65 points

Answer 1

8.) Sum: the product of two added factors

2 times: Multiplied by 2

The answer is $2(a + b)$

9.) We know Jack currently has $205. It says he spends $2 each day. This means that each day his current value changes by -$2.

This means your answer is $205 - 2d$

10.) If $55 is the total amount you are spending, then this means you put it on the right side of the equation:

$x + y + z = 55$

Each book is $7.50, so you are buying b books.

Each pencil is $3, so you are buying p pencils.

Each eraser is $2, so you are buying e erasers.

This means that $7.50b + 3p + 2e = 55$
