Which expressions result in a negative number? choose all answers that are correct. a. –84 ÷ 21 b. c. –7.3 – (–4.3) d. –4.2 • (–3.5)

Amount earned by Sharon per item sold = $25

Base salary of Sharon per week = $100

Amount that needs to be earned by Sharon per week = 975

Let us assume the number of items sold by Sharon per week = x

Then

100 + 25x = 975

25x = 700 - 100

25x = 600

x = 600/25

  = 24

So Sharon needs to sell 24 items to earn a total of 975 per week. I hope you have understood the method of solving such problems.
