Answer:
a.70.95
b. 7.5
Step-by-step explanation
If you divide 2.40 by 32, you get the ratio of the tip to cost, which is 0.075, or 7.5 percent. Multiply 66 by 1.075, which includes both the cost and the tax.
These steps include statements B, C, and D. Drawing a line from the segment to any point on the fold line, which is statement A, is not included in these steps because it is not needed. Thus, choice A is not a step in using paper folding to find the midpoint of a line segment.
