Answer: There are 5 pairs of jeans which Elisa can bought.
Step-by-step 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,
[tex]x+y=9\\\\\implies x=9-y----------------(1)\\\\and\\\\43x+34y=334-----------------(2)[/tex]
So, we will solve it using "Substitution method":
Put the value of Eq(1) in Eq(2), we have
[tex]43x+34y=338\\\\43(9-y)+34y=338\\\\387-43y+34y=338\\\\-9y=338-387\\\\-9y=-49\\\\y=\frac{49}{9}=5.44\\\\y=5\ approx.[/tex]
Hence, there are 5 pairs of jeans which Elisa can bought.
