Answer:
[tex]90\% \times 85[/tex]
Step-by-step explanation:
According to her
Discount = 10%
Total Cost = $85.00
So, Discount amount = [tex]10\% \times 85[/tex]
= [tex]\frac{10}{100} \times 85[/tex]
= [tex]8.5[/tex]
Amount to be paid = $85.00 - $8.50
= $76.50
Another way
Since we are given that 10% is discount
So, she need to pay 90% of amount
So, Amount to be paid =[tex]90\% \times 85[/tex] = $76.50
Hence the expression would give Rhonda the same result in one step is [tex]90\% \times 85[/tex]
