Vince borrows $900 to buy a couch. He will pay off the loan by paying 1.5% simple interest for 2 years.
Vince incorrectly calculates the amount he will pay back using the expression below.

square root

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
