Answer:
Step-by-step explanation:
7C + 2L=$6.50
10C + 3L=$9.50
3C + L = $3
6C + 2L = $6
7C + 2L=$6.50
C = $0.50
10(0.50) + 3L = $9.50
5 + 3L =$9.50
3L = $4.50
4.50/3=$1.50
L=$1.50
Answer:
Cookies = $0.5
Lemonade = $1.5
Step-by-step explanation:
6.5 = 7x + 2y
9.5 = 10x + 3y
-10(6.5 = 7x × 2y)
17(9.5 = 10x +3y)
-65 = -70x -20y
+66.5 = 70x 21y
1.5 = 1y
1.5 = y
6.5 = 7x + 2(1.5)
6.5 = 7x + 3
3.5 = 7x
0.5 = x
