Answer:

54.35d + 0.09×425 ≤ 320

Step-by-step explanation:

The amount Jayden will spend on rental for d days and 425 miles will be ...

54.35d + 0.09×425 ≤ 320 . . . . . the basic inequality

This can be simplified to ...

54.35d +38.25 ≤ 320

or ...

54.35d ≤ 281.75 . . . . . . . subtract 38.25

_____

Divide by the coefficient of d to find the solution:

d ≤ 5.184

Jayden can rent the car for 5 days while staying within his budget.

To solve for the A or the principal amount plus interest you can use two formulas:

A = P + I

Where: P = Principal
I = Interest

or you can use

A = P (1+ rt)

Where: P = principal
r = rate in decimal
t = time in years

With your given you can use the second one, without having to use the first.
Given that the Principal amount is $222 and the rate is 12% and time is 10 years, we first need to convert your rate into decimal by dividing the value in percent by 100 which will yield 0.12.

Then now we can just input the data that you know into the formula:
A = P(1+ rt)
= $222(1 + (0.12)(10))
= $222(2.2)
= $488.40

Your A is then equal to $488.40

If you need to get the simple interest all you need to use is the first formula given:

A = P + I
for the interest you transpose the P to the side of the A and you will get:
I = A - P
= $488.40 - $222
= $266.40

$266.40 is the added interest to the principal amount.

Answer:

B) Mode doesn't change.

Step-by-step explanation:

Given:

A set of data with 16 being added to the set.

The mode of a given set of data is the data that is repeated the most number of times.

Here, 19 is repeated 3 times, so the mode is 19.

Now, if a number other than that of 19 being added, doesn't affect the mode of the data set as 19 will still be 3 times and adding 16 will not increase its number in the set.

So, the correct option is B.
