Answer:
the amount saved by her for two jeans is $16
Step-by-step explanation:
Given that
Misty purchased two pairs of jeans that cost $24 each
But they were on sale for one third of the total price
We need to find out the amount save
So, the amount saved is
= $24 × 1 ÷ 3 ×2 jeans
= $16
Hence, the amount saved by her for two jeans is $16
