Answer:
Step-by-step explanation:
It would be answer b, because if you were to solve this, then this is how you would do it (in the most effecient way):
2.5x + 1.2 = 1.2x + 4.2
2.5x + 1.2 - 1.2 = 1.2x + 4.2 - 1.2
2.5x = 1.2x + 3
2.5x - 1.2x = 1.2x - 1.2x + 3
1.3x = 3
1.3x/1.3 = 3/1.3
x = 3/1.3
4.34375 would be the approximate answer.
Answer:
13 dollars and 44 cents, 56 cents.
Step-by-step explanation:
134 dollars are 40 cents = 134.4 dollars.
10b = 134.4

13 dollars and 44 cents
There are 24 cookies to a batch
24c = 13.44
c = 0.56.
so each cookie costs 56 cents
