Answer:
6 pairs.
Step-by-step explanation:
Rebecca bought x pairs of socks and received a 20% discount.
Each pair of socks costs = $4.99
So cost of x pairs = (4.99x)
cost after 20% discount on x pairs of socks = x(4.99 - 20% of 4.99)
= x(4.99 - 0.998)
= 3.992x
Total cost of socks = $23.95
3.992x = 23.95
x = [tex]\frac{23.95}{3.992}[/tex]
= 6 pairs.
