Answer: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
<u>(-)(-) (-) </u>
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
1 bag per 5 minutes.
If you divide 15(total amount of min) by 3(bags of popcorn you popped) you will see you popped 1 bag per 5 minutes.
