5x(6+2) because 6+2=8 ans 5x8=40
Answer:
You can buy 7 waffle cones.
Step-by-step explanation:
Let sundae = x
Let waffle cones = y
4.25x + 3.75y ≤ 50
4.25 (5) + 3.75y ≤ 50
21.25 + 3.75y ≤ 50
3.75y ≤ 28.75
y ≤ 7.666666666
* round to the nearest whole to get 7
15(100) + 5d+ 20(50) + 7d=d
1500+ 1000+ 12d=d
2500+12d=d
