At a school dance. juan paid $2.05 for 1 soda and 2 pretzels. keisha paid $1.85 for 1 pretzel and 2 sodas. what is the cost of 1 pretzel and 1 soda?

1 pretzel is 0.75$

1 soda is 0.55$

Step-by-step explanation

suppose

soda=x

pretzel=y

according to Juan

x+2y=2.05(1)

according to Keisha

2x+y=1.85(2)

multiply 2 to the 1 no. and do subtraction from 1 no. to 2 no.

2x+4y=4.1

2x+y   =1.85

(-)(-)    (-)          

   3y=2.25

     y=2.25/3

       y=0.75

place y=0.75 to 1 no

 x+2×0.75=2.05

  x=2.05-1.5

  x=0.55
