Problema Solution
Nathan receives a weekly allowance of $8. Nathan can earn $5 more for every 100 algebra problems he completes beyond the usual number. In 12 weeks Nathan wants to have saved enough to buy new algebra books that cost $210. If he saves all his money, how many algebra problems does he have to complete to earn what he needs?
Answer provided by our tutors
Let number of algebra problems solved=x
So, 8*12+5x=210
96+5x=210
5x=114
x=22.8
Number of algebra problems Nathan need to solve=22.8*100=2280
