PLEASE HELP ME!!Matthew is planning a party and found pizzas for $5 each and drinks for $1 each.
Write an expression that represents how much he will spend. (p = pizza, d = drinks)

How much will he spend if he buys 4 pizzas and 5 drinks?

Can he afford 8 pizzas and 10 drinks if he has $45 to spend?

Give any combination of the # of pizzas and drinks he can afford if he has $50 to spend.
