The answer to this problem is 5.
Yes you can and you do that by multiplying $42×1.30=54.60 and then $54.60×1.25=68.25
Each bicycle gives a profit of around 60 dollars.
2400/60= 40
The store must sell around 40 bicycles every month.
It is easier (for me anyway) to find 10% then work around that.
Following that path would mean that, by making a table:
100% = 220
10% = 22
5% (Which is half the 10) = 11
