Step-by-step explanation:

Question, Which equation shows how to find a, the amount of money spent on supplies after the coupon

The statement,  After a coupon, the total came down to $418

Im kinda confused, but if you/the question means find out how much the coupon was, 457 - 418 = 39, If i dident answer the question correctly please comment, ill probably reply

All you have to do is subtract $457-$418 which equals $39.00 (thirty-nine dollars)
