Answer:
x = 10
Step-by-step explanation:
3x - 9 = 21
add 9 on both sides:
⇒ 3x - 9 + 9 = 21 + 9
⇒ 3x = 30
divide 3 on both sides:
⇒
⇒ x = 10
to check answer, substitute x by 10 on the original equation:
⇒ 3x - 9 = 21
⇒ 3 x 10 - 9 = 21
⇒30 - 9 = 21
⇒ 21 = 21
Answer:
10%
Step-by-step explanation:
To find the percent increase in the price of the insurance policy, we first need to take the total value of the original price of the insurance policy and subtract it to the new price of the insurance policy.

New Price = $2,200
Original Price = $2,000
Price Increase = 2,200 - 2,000
Price Increase = 200
Now to find the percentage increase, we take the price increase and divide it by the original price and multiply it by 100.
Total increase % =
Total increase % =
Total increase % =
