Robert invested $800 in a bank account. The account has an annual interest rate of 5.5%. How much money will be in the account after 12 years.

Step-by-step explanation:

since our formula is , then you would plug in 800 as 'P', 1.055 as 'r' since you shift the decimal 2 digits to the left then add 1 (as a whole number) and raise it to the twelfth power.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
