Exam The formula for finding the change in
CPI is [(new-old)/old] for different
baskets of goods and services. What is
the change in the CPI if the new price
for transportation services is $100 and
the old price was $80?
A. 25%
B. 15%
C. 10%

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

10 glasses of juice could be made with 5 carrots, 1,500 orange juice, 2,000 papaya juice.

there are infinitely many solutions.

60: 45 =12: 9 =4: 3 so the answer is 4: 3
