If we take S=3, and R=2, then the answer is C, since 3*3*2 = 18, and 3+3+2 = 8, and 8 != 18
Okay, so you need at least $100 in your account to avoid the fee.
You currently have $247.
And you also take out $20, every week.
So first, work out the maximum amount of money you can take out before reaching the limit. (247 - 100 = 147).
Now that we know you can take out $147 max, you just need to divide it by $20, because that's how much you take out every week. (147 ÷ 20 = 7.35 weeks.) But of course, the question is asking for the answer in weeks, so you round the answer down to 7 weeks.
You can last 7 weeks by taking out $20 every week from your $247 balance to avoid the low balance fee.
Step-by-step explanation:
7 X + 8 = X+12 + 3X+20
3 X = 24
X= 8
m< RPQ = 8+12 = 20
(x² - 4x - 32) / (x² +7x +12)
factor both the numerator and denominator
[(x-8)(x+4)] / [(x+3)(x+4)]
Since (x+4) is in both the numerator and denominator, it can be cancelled out:
(x-8)/(x+3) is the simplified form
