Question

Elisa brought 9 pair of pants for a total of $338. She brought dress pants for work, and they coasted $43 each. She also brought some jeans and those were $34. How many pair of jeans did Elisa brought?

Answer 1

Answer: There are 5 pairs of jeans which Elisa can bought.

Explanation:

Since we have given that

Total cost = $338

Cost of each pants = $43

Cost of each jeans = $34

Number of pairs of pants and jeans= 9

Let the number of pants be 'x'.

Let the number of jeans be 'y'

According to question, it becomes,

`x+y=9\\\\\implies x=9-y----------------(1)\\\\and\\\\43x+34y=334-----------------(2)`

So, we will solve it using "Substitution method":

Put the value of Eq(1) in Eq(2), we have

`43x+34y=338\\\\43(9-y)+34y=338\\\\387-43y+34y=338\\\\-9y=338-387\\\\-9y=-49\\\\y=(49)/(9)=5.44\\\\y=5\ approx.`

Hence, there are 5 pairs of jeans which Elisa can bought.
