option (B) 25 ✔
break it up into simpler shapes. See the photo.
There is:
trapezoid
A = 0.5(3.2+6.5)4.5
= 21.825
triangle
A = 0.5(2.7)4.5
= 6.075
rectangle
A = 1.8(4.5)
= 8.1
Total Area = 21.825 + 6.075 + 8.1
= 36
Answer:
A. c = 0.31b
Step-by-step explanation:
$7.44 = 24 juice bottles
[Divide by 24 on both sides]
$0.31 = 1 juice bottle
The cost is equal to the amount per juice bottle times the number of juice bottles, so:
c = 0.31b
(A trick to use when you don't know the answer: If there are multiple answers with the same numbers but the decimal places are in different places, it is probably one of those answers.)
