Answer: the best coupon for this case is WELCOME25, and the cost will be $30.

Step-by-step explanation:

We know that:

Price for pans = $22

Price for pots = $9.

If the customer buys two pots and one pan, he would pay::

C = 1*$22 + 2*$9 = $40.

If the customer uses the coupon 2POTSFOR1

Then he will pay only one of the pots, and the total cost will be:

C = 1*$22 + 1*9 = $31.

If the customer uses the WELCOME25 coupon, then the cost will be a 75% of the original cost.

if 100% = $40

then:

 75% = C

Where

We can take the quotient of these equations and get:

 (C/$40) = (75%/100%)

C = (75%/100%)*$40

C = 0.75*$40 = $30

Then the best coupon for this case is WELCOME25, and the cost will be $30.
