The unknowns in this problem are A. The number of boys and the number of girls in the class.

Joshua sold his bike for 10% less than payed for it. If he sold the bike for $585, how much did he pay for it.
Troyanec [42]

Answer: $650

Step-by-step explanation:

If he sold the bike 10% less than the original amount which means he sold it as a 10% discount so the person has to pay 90% of the price. And 90% of the price has to equal $585  so we could set up an equation and solve for the price.

90% * x =  585

0.9 * x = 585

0.9x = 585

x = 650  

Which means he paid $650 for the bike.
