pp+s=100.90

pp+c=244.50

c=5s

We solve this system

From the 1st s=100.90-pp, from the 2nd pp=244.50-c => s=100.90-244.50+c=c-143.60

c=5s=5(c-143.60)=5c-718

4c=718

That was not the answer the teacher gave. It was $179.50 for the coat. How do I get this answer?

Divide last equation by 4 c=718/4=179.5
