this is emberassing. I cant solve for the life of me my little sisters homework.

Guiseppi's pizza had orders for 729$ of pizzas. the prices were 19$ for a large, 14$ for a medium, and 10$ for a small. the number of large pizzas was one less than three times the number of medium pizzas. the number of small pizzas was two more than twice the number of medium pizzas. how many of each pizza was ordered

is it just the word problem getting to you?

19*L + 14*M +10*S = 729
L = 3M - 1
S = 2M + 2

does that help?

Oh goodness that was retardedly simple. Thank you !
