The school cafeteria sells two kinds of wraps: vegetarian and chicken. The vegetarian wraps cost $1.00 and the chicken wraps cost $1.50. Today they made $149.00 from the 105 wraps sold. How many wraps sold were vegetarian?

Respuesta :

Answer:

17 wraps

Step-by-step explanation:

Given data

let the  number of vegetarian wraps be x

and chicken wraps be y

so

x+1.5y= 149------------1

and

x+y= 105----------------2

the systems of equation for the problem is

x+1.5y= 149

x+y= 105

from 2

x= 105-y

put this in 1

105-y+1.5y= 149

105-0.5y= 149

-0.5y= 149-105

-0.5y=44

y= 44/0.5

y= 88

put y = 88 in 2

x+88= 105

x= 105-88

x= 17
