He has $170 minus the $25.50 fee= $144.50 left. If each session is $10.50, then divide 144.50 by $10.50 and you get 13.76. He will have enough for 13 help sessions
Answer:
1 1/2
Step-by-step explanation:
When you are subtracting a negative number is is the same as adding a positive. So the problem is really 5/8 + 7/8, since the denominators are the same, just add the numerators to get 12/8 divide the top and bottom by 4 to get 3/2 or 1 1/2, if I divide 3 by 2.
