Your part time job pays you $14/h. You work approximately 12 hours/week.

kirill115 [55]

Answer:

<u>BOX 1 </u>= 672.00

(14 * 12 = 168

168 * 4 = $ 672 )

2. <u>BOX 2</u> = 282.95

(Cell phone= $45 A MONTH

Eating outside = $50 A MONTH

12 .50 * 4 = 50 (4 WEEKS A MONTH )

Transportation = 131.2 A MONTH

32.80 * 4 = 131.2 (4 WEEKS A MONTH )

Movie = $16.75 A MONTH

Charity = $ 40 A MONTH

10 * 4 (4 WEEKS A MONTH )

<u> MONTHLY EXPENSE </u> = 45 + 50 + 131.2 + 16.75 + 40

<u> MONTHLY EXPENSE </u> = 282.95 )

3. <u>BOX 3</u> = 389.05

Money that can be saved = Monthly income - Monthly expense

Money that can be saved = 672 - 282.95

= 389.05
