b. shamaya has a budget of $100 dollars for school supplies for the
school year. if this is her first school supply purchase for this year,
how much money does she have left in her budget for school
supplies?

a.  $17.83

b.  $82.17

Step-by-step explanation:

a.

We need to find total cost of all the items.

2 package of pencil for 1.98 each: Total = 1.98 * 2 = 3.96

1 binder for 7.69:  Total = 7.69

1 divider for 2.69:  Total = 2.69

1 pencil box for 3.49:  Total = 3.49

We sum all of these to get:

3.96 + 7.69 + 2.69 + 3.49 = $17.83

b.

She only spent 17.83 and she had 100 dollars. So we subtract amount spent (17.83) from total (100) to get remaining balance.

100 - 17.83 = $82.17

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
