would you please check my work and make changes for errors? thanks ann

problem: joe bought 3- topping sundae for 15.25 and a 5 topping sundae for 17.75.

write and solve a system of linear equations to find price of each topping and a plain sundae(no toppings).

I wrote:

x + 5y = 17.75

-x+ -3y= 15.25

2y = 2.50

y = 1.25 price per topping

x = 15.25 - 3(1.25)

x = 15.25 - 3.75

x = 11.50 price per plain sundae
