Question

Angelique makes beaded jewelry. The graph below shows the number of beads on varying cord lengths.

A necklace contains 88 beads. Based on the information above, which is the best estimate for the cord length?

a. 21 inches
b. 26 inches
c. 34 inches
d. 36 inches

Answer 1

34, or of course "C"

Explanation:

We can infer 21 inches is already to low to for 88 beads, and it's not 26 inches because 26 inches is needed for around 25 beads, so we can say "A" and "B" are too low for 88 beads, 34 inches would be the right answer to go.

Answer 2

This would be the solution for this problem:
88 = 2.52x + 1.61[transpose 1.61 to the other side]
88 - 1.61 = 2.52x[subtract 1.61 from 88]
86.39 = 2.52x[divide both sides by 2.52 to get the value of x]
86.39/2.52 = x
34.28 = x
The answer would be C.
