Victor buys 4 sleeves of golf balls. He has coupons for $0.75 off the regular price of each sleeve. After using the coupons, the total cost of the golf balls is $11. What is the regular price of each sleeve of golf balls?

Each sleeve was $3.50

His coupon is for .75 off each sleeve. He got four sleeves, so you’d multiply .75 x 4 to get 3.

Then add 3 + 11 to get the total price he would have paid without the coupon (14).

Then divide 14 by 4 (the number of sleeves he bought) to get 3.50

No a triangle cannot be formed because when you add the two smallest number together (which would be 11) the have to be bigger than the number it is "against" ( which would be 12)
