Question

Morgan buys 6 gel pens. He has a coupon for $0.80 off the price of one gel pens. The total cost after the coupon is applied is $9.52. Solved the equation 6p-0.80=9.52 to find the price p in dollars of each gel pen

Answer 1

6p - 0.80 = 9.52

Your goal is to isolate p.

You can add both sides by 0.80 to cancel 0,80 on left side:

6p - 0.80 + 0.80 = 9.52 + 0.80

6p = 9.52 + 0.80

6p = 10.32

Now divide both sides by 6:

6p / 6 = 10.32 / 6

p = 10.32 / 6

p = 1.72

So the cost of each gel pen is $1.72.

Hope this helps.
