Question

Girl works at a book store she gets $145 per week plus 5% for every book sold she wants to have $600 by the end of the week, how many books does she need to sell?

Answer 1

she makes $145
5% of $145 is $7.25 [found by 145× 0.05 =7.25]
600-145=455
455÷7.25= 62.75
so let's call it 63 books a week
or
9 books a day for 7 day
