Answer:
(4,5)
Step-by-step explanation:
Which question? The picture is black
<span>d=drinks
p=pretzels
1st eq. 3d+3p=9.00
2nd eq. 4d+2p=8.50</span>
multiply
1st eq by 2
6d+6p=18.00
<span>multiply
2nd eq by 3
12d+6p=25.50
subtract
-6d=-7.50
d=1.25
3p=9.00-3d</span>
3p=9-3.75
<span>3p=5.25
p=1.75
price of a pretzel=$1.75</span>
<span> price of a drink = $1.25</span>
