A palm reader gets paid $80 for each palm she reads, and her goal is to earn $2240 reading palms this month. If she has already read 4 palms this month, how many more palms must she read in order to reach her goal?
A. 24 because the palm reader must read 28 palms to reach $2240 as she charges $80 for each palm. Since she already read 4 palms it should be subtracted from 28 to obtain 24.
