Answer:
28.35
Step-by-step explanation:
Let cost of 1 coat = c.
Let cost of 1 umbrella = u.
7c + 12u = 399.45;
3c + 25u = 503.80
Multiply both sides of the first equation by 25.
Multiply both sides of the second equation by 12.
175c + 300u = 9986.25
36c + 300u = 6045.6
Subtract the second equation from the first equation eliminating u. Then solve for c.
139c = 3940.65
c = 28.35
Answer: A coat costs $28.35.
