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>.
It is not always possible to construct a triangle from a given side length and two angles. If the two given angles add to more than 180°, the sides of the triangle will diverge and never meet.
