To obtain the charges paid for the first 4 days, you must use the given explicit rule given:
f (n) = 28n + 32
Where:
<em>n = Number of days the person rents the car.</em>
As we need to obtain the charges to 4 days, we replace this value in the explicit rule:
f (n) = 28n + 32
f (4) = 28(4) + 32
f (4) = 112 + 32
<u>f (4) = 144</u>
With these calculations, <u>you can identify the charges paid for the first 4 days are $144</u>, <em>where $112 is the money by each day of the four days and $32 is the base fee</em>.
Answer: She deposits 50 dollars per month right? But as known her parents deposited her 2,500. So, it will take her 50 months to complete the amount of 5000 dollars needed for college.
Step-by-step explanation: Im not good with equations but here we go.
First: AS we know the account already had 2,500, and every month she deposits 50$.
What we can do is to divide 2,500 divided by 50 which will be 50.
