a.) If Katie finds 4 new customers and still keeps the old one’s will she make an additional $150 per week?

She mowed 35 lawns per week. And it’s $6 per lawn. With this rate she earned:
35*6 = $210
She want to earn $150 additional or a total of $210 + $150 = $370
Her new rate is $8 per lawn. The new number of customers is 4 + 35 = 39. This time she will earn:
39*8 = $312
Since 312 < 370 she sill not make an additional $150 per week.
