the cost of 1 hamburger and 1 shake is $1.89

Answer 2

Cost of 1 hamburger and 1 shake is​ $1.89

Step-by-step explanation:

Assume:

Cost of hamburgers = h

Cost of milkshakes = m

For Jack

2h + 3m = $4.21.......Eq1

For Jill

3h + 2m = $5.24.........Eq2

Eq1 + Eq2

5h + 5m = 9.45

divide by 5

h + m = $1.89

So,

Cost of 1 hamburger and 1 shake is​ $1.89
