Level Numerical Expression Number of Stairs
1 32 x 1 32

Based on this relationship, how many stairs will Joaquin count by the 23rd level?
A. 165
B. 55
C. 756
D. 736

Answer 1

D

Explanation:

As soon as you see a number times 1 thats how you can find your unit rate, or constant of proportionality.

So since we know that we are going by 32's, we would do 32 23 times, in other words, 32x23

And when you use a CALCULATOR or pencil and paper you get D, which is 736 stairs
