The value of the CPI (Consumer Price Index) is calculated by dividing first the current period price by the base period price and multiply the quotient by 100. Using the first set of values, we get base period price. 
                                CPI = (current period price / base period price) x 100
                                 191 = (93.11 / base period price) x 100
                                          base period price = 48.75

Then, using this base period price and the second current period price, we solve for the second CPI
                                CPI = (76.05 / 48.75) x 100
                                  <em>CPI = 156
</em>Therefore, the answer to this item is letter C. <em>

Kelly found the area of the composite figure below and showed her work on a quiz. Her teacher marked her answer incorrect.
Stella [2.4K]

Answer:

446.75 y^2

Step-by-step explanation:

First, Kelly found the area of a circle, not half a circle, which is on top of the figure. She also shouldn't have subtracted the area of the circle by the airea of the base, as she is trying to find the area of the ENTIRE figure.

.5 TIMES pi times 9^2 = 122.75

the second part, calculating the square base is correct..

122.75+324 = 446.75 y^2
