Answer:
21) $90 22) $144 23) $240.5
Step-by-step explanation:
21) Cost to Store(CTS): 75 Markup(M): 20
Turn 20% into 0.20
Multiply the CTS, 75, by 0.20 to get 15
Add 15 and 75 together to get 90
22) CTS: 90 M:60
Turn 60% into 0.60
Multiply the CTS, 90, to 0.60 to get 54
Add 54 and 90 together to get 144
23) CTS: 130 M:85
Turn 85 into 0.85
Multiply the CTS, 130, to 0.85 to get 110.5
Add 110.5 and 130 together to get 240.5
67.73 first day + 86.48 second day
67.73 + 86.48 = 154.21
Then you subtract the total from the first and second day from 200.
200 - 154.21 = 45.79
So, Julie has to ride 45.79 miles on day 3 to complete the 200 miles.
Hope this helps. :)
