The CPI for 1930 was 16.7, while for 1939 it was 13.9. If an item costs $100 in 1930, how much would it have cost in 1939?

Step-by-step explanation:

If the CPI for 1930 was 16.7, while for 1939 it was 13.9, the change in CPI will be 16.7 - 13.9 = 2.8. The amount lost within the year 19.30 to 1939 if the cost of the item in 1930 is $100 will be expressed as;

= 2.8/16.7 * 100

= 280/16.7

= $16.8

The amount the item would have cost in 1939 will be $100 - $16.8 = $83.2

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

2.56 is the width of the garden
