Yes, because two batches of dough equals 48 cookies. So she would need 3 batches, equaling to 72 cookies.
I'm pretty sure the answer is A.
Answer:
Step-by-step explanation:
Let chocolate bar cost be c and blow pop cost be b
<u>Then we have equations:</u>
- 5c + 8b = 23.25
- 2c + 13b = 21.55
<u>Multiply the first equation by 13 and the second one by 8 and subtract:</u>
- 13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55)
- 65c - 16c = 129.85
- 49c = 129.85
- c = 129.85/49
- c = 2.65
Chocolate bar costs $2.65
The answer is that feet and 5+7 and times
