Question 6

Julie's Restaurant purchased some new equipment for $5,750. It was given a special discount of 5% plus a sales tax of 6%. What was the total cost?
A) $5,462.50
B) $327.75
C) $5,790.25
D) $287.50

Accepted Answer

To find the total cost, we need to first calculate the discount given:
Discount = 5% of $5,750 = 0.05 x $5,750 = $287.50

Now, we can find the cost after discount:
Cost after discount = $5,750 - $287.50 = $5,462.50

Next, we need to add the sales tax to this cost:
Sales tax = 6% of $5,462.50 = 0.06 x $5,462.50 = $327.75

Therefore, the total cost = cost after discount + sales tax = $5,462.50 + $327.75 = $5,790.25

Hence, the best choice is C.
