Solve a word problem involving simple interest
Question
Robin deposited $31,000 in a bank account with an annual interest rate of 5.2%. How much interest was earned in 3
years?

The interest is $4836

Step-by-step explanation:

Simple Interest SI = (PRT)/100

Principal P = $31000, rate R is 5.2% and Time T = 3 years

SI = (31000×5.2×3)/100

SI = 310×5.2×3

SI = $4836

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
