Answer:
the answer is the second option which is 6⅓
<span>No, this is not proportional. After 1 week she would have $280+$30=$310. After 2 weeks she would have $310+$30=$340. The proportional time is "2 to 1", but the proportional savings is $340 to $310, which is a different proportion.</span>
Answer:
x = 0
Step-by-step explanation:
-[(3^x - 1)(5^x - 1)] + 1 = 1
Subtract 1 form both sides
-[(3^x - 1)(5^x - 1)] = 0
Divide both sides by -1
(3^x - 1)(5^x - 1) = 0
Equate the factors to 0
3^x - 1 = 0
3^x = 1
Use ln both sides
ln(3^x) = ln(1)
xln(3) = 0
x = 0
5^x - 1 = 0
5^x = 1
Use ln both sides
ln(5^x) = ln(1)
xln(5) = 0
x = 0
The only solution is x = 0
36% = 0.36
0.36x3.85= 1.386 or 1.39
1.39 will be the tax increase
1.39+ 3.85= 5.24
Your answer will be $5.24
