Answer:

Step-by-step explanation:

let price of  one pretzel=x

price of one soda=y

3x+4y=11.25   ...(1)

5x+2y=8.25    ...(2)

multiply by 2

10x+4y=16.50   ...(3)

(3)-(1) gives

7x=5.25

x=0.75

from (1)

3(0.75)+4y=11.25

2.25+4y=11.25

4y=11.25-2.25

4y=9

y=9/4=2.25

cost of one pretzel=$0.75

cost of one soda=$2.25
