Question

Sofia and Max went to the fair. Sofia ordered 2 hotdogs and 1 soda and the cost was $5.00. Max was starving so he ordered 5 hotdogs and 3 sodas for $13.00. Write a system of equations, using “h” for number of hotdogs and “s” for number of sodas. Then solve to show how much each hotdogs and each soda costs.

Answer 1

Answer:

Hotdog=$1

Soda=$3

Step-by-step explanation:

solve the equation you form simultaneouly

2h+1s=$5

5h+3s=$13

equalize s by multiplying the first equation by 3 and the second by 1

6h+3s=$15

5h+3s=$13

SUBTRACT

h=$1

substitute $1 in h for the first equation

$6+1s=$15

3s=15-6

3s=9

s=$3
