<span>A. Consumer price index measures the change in prices of specific good and services over time. The consumer price index (CPI) is an estimate of prices that are collected periodically that represent the item/goods. CPI is based on the overall cost of a fixed basket of goods a typical costumer would buy rather then the same basket in the year.</span>
X=17/2
Decimal form : x=8.5
Let x be the price of a cupcake.
There are 24 cupcakes so it will be 24x.
Solution:
24x+16=52
24x=52-16
24x=36
Divide both sides by 24
X=1.5.
The price of each cupcake is 1.5$
If you are using a calculator, simply enter 16÷72×100 which will give you 22.22 as the answer.
Answer:
Part A) The triangles ABC and EDC are similar by AAA, because the three internal angles are equal in both triangles
Part B) The width of the river is about 
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent
Part A) we know that
In this problem , triangles ABC and CDE are similar by AAA, because its corresponding angles are congruent
so
m<DCE=m<ACB -----> by vertical angles
m<EDC=m<ABC -----> is a right angle
m<DEC=m<CAB -----> the sum of the internal angles must be equal to 180 degrees
Part B) we know that
The triangles ABC and EDC are similar -------> see Part A
therefore

substitute the values and solve for AB
