Answer:
Step-by-step explanation:
- 100
+ 120 = 20
-140 = -20
+160 = 20
so every time he sold it, he gained 20 and lost 20 every time he bought it back
32.5
7h+1.50d
step 2: plug in the hours he worked and the amount of deliveries made.
(7x4)+(1.50x3)=32.5
$63000 more
Just subtract $23000 from $86000.
