Question

Suzanne bought a sweater at the sale price of $25. The original cost of the sweater was $40. What percent represents the discount that Suzanne received when buying the sweater?

Answer 1

Answer:

37.5%

Step-by-step explanation:

25 + (1 - m) * 40

25 = 40*1 - 40*m

25 =40 - 40m

25 = 40 + (-40m)

-40 = -40

-15 = 40m

/40 = /40

=0.375 = m

37.5% = m

Answer 2

X/100 = 25/40
25x100 = 40x
2500/40 =62.5 %
