Answer:

n = m - a

Step-by-step explanation:

Given that:

The expression of the formula  a = m - n

where;

a = actual cost of an item

m = original price

n = amount of coupon in dollars

The objective is to solve for the amount of the coupon.

In order to determine the amount of the coupon, we need to make n which is the amount of coupons in dollars the subject of the formula from the given expression.

So if a = m - n

a + n = m

n = m - a
