Preet wants to determine the rate of change in gas prices. In week one of his study, he found the price to be $2.86 per gallon. In week five of his study, he found the price to be $3.14 per gallon. What is the average rate of change in gas prices, based on the data collected by Preet?

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
