Answer:
Step-by-step explanation:
Any time you have compounding more than once a year (which is annually), unless we are talking about compounding continuously, you will use the formula
Here's what we have:
The amount after a certain time that she has in the bank is 4672.12; that's A(t).
The interest rate in decimal form is .18; that's r.
The number of times the interest compounds is 12; that's n
and the time that the money is invested is 3.5 years; that's t.
Filling all that into the formula:
Simplifying it down a bit:
Raise 1.015 to the 42nd power to get
4672.12 = P(1.868847115) and divide to get P alone:
P = 2500.00
She invested $2500.00 initially.
Answer:
4:3
Step-by-step explanation:
For every £1.00 a company spends on advertising, it spends £0.75 on its website.
From the above question:
The ratio is given as:
Amount spent on advertising : Amount spent on website
= £1.00 : £0.75
Convert ratio sign to division
= 1/0.75
Multiply Numerator and Denominator by 100
= 1 × 100 / 0.75 × 100
= 100/75
= 4/3
= 4 : 3
Therefore, the ratio in its simplest form = 4:3
0.76 is the answer
