he GDP deflator in year 4 is 120 and the GDP deflator in year 5 is 130. The rate of inflation between years 4 and 5 is

8.33%

Explanation:

The GDP deflator in year 4 is 120

The GDP deflator in year 5 is 130

Therefore the rate of inflation between year 4 and year 5 can be calculated as follows

= 130/120

= (1.0833 -1) × 100

= 0.0833 × 100

= 8.33%

Hence the rate of inflation between year 4 and 5 is 8.33%

x=3

step-by-step explanation:

this is really simple i saw that there was only one term (5x) and thought if that was 15 what would i have to multiply everything else to get it there? well if 5x became 15 then x would have to be 3 so plug the 3 in the x for the other equations and you get 15 for the other ones. so there you go. : )
