Agroup of friends are playing golf. the total cost of the round of golf is $108. each person in the group has the same coupon. the total cost of the round with the coupons is $76. how much is the coupon worth?

For this equation, we can let c = the value of one coupon 
4c = 108 - 76 
4c = 32 
c= $8 

Hope this helped, and if it did I'd appreciate if you marked me as brainliest as I need it to get to a higher rank. If you need any more help, feel free to add me and/or message me :)
