At a local fair, a hamburger cost $2.50, and a drink cost $1.50. Write an expression that represents the cost of x number of hamburgers and y number of drinks.

What the proper work

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
