The equation would be
x+(x+2)+(x+2+2)=105
3x+2+2+2=105
3x+6=105
3x=99
x=33
so the answers would be 33, 35 and 37
Answer:
x=17
Step-by-step explanation:
3x-3=6(x-10)
3x-3=6x-60
57=3x
x=17

Hello there! So, the formula for compound interest is P(1 + r/n)^nt. P = principal, r = rate, n = number of times compounded per year, and t = time in years.
a. Just by looking at the numbers, I would say that Gavin should take the first option of 9% compound interest annually.
b. I say this, because you're gonna earn a lot more. Just by solving the question for the amount in 5 years for each account, the first opinion will earn you $3,077.35, and the other option will only give you $2,265.42 in 5 years. Keep in mind that compounding quarterly means 4 times per year. With a low interest rate, it's no surprise that the first option would be a better choice.
