Mrs. Santos is 29, 44-15=29
$7.20 $28.8 $18.8 $225.6 $225.6
4 $10 12 .25 $56.4
X___ -_____ X____ X_____ +_____
$28.8 $18.8 225.6 $56.4 $282
You multiply $7.20 by the 4 hours she's working and you'll get $28.80. Then you would subtract the $10 from your answer and get $18.80. Then you'd multiply $18.80 by 12 for the mouths she's working and get $225.60. Next you multiply $225.60 by .25 from the grandparents and get $56.40. Finally you add $225.60 to $56.40 and get $282 in her savings account.
Step 1 (simplify):
3+5x(2-1)
8 x 1
Step 2 (solve):

8 is your answer. Hope this helps :)
