Cost for travelling 1 mile = 3.75
 cost 2 miles  = 5.25
cost 3 miles = 6.75
 cost 4 miles = 8.25

rate of change = 1.5 dollars per mile

Answer:

rate of change of the cost in dollars with respect to the number of miles= 1.5

Step-by-step explanation:

We have been given the function y = 3.75 + 1.5(x-1)

Let us simplify this equation

y = 3.75 + 1.5(x-1)

y= 3.75+1.5x-1.5

y = 1.5x+2.25

On comparing this equation withe the slope intercept form y = mx + b, we get

m = 1.5

b = 2.25

here x represents distance in miles and y represents the cost in dollars. So, the  rate of change of the cost in dollars with respect to the number of miles would be equal to the slope of the line.

Thus, we have

rate of change of the cost in dollars with respect to the number of miles

= slope

= 1.5

Eduardo earns a base salary of $30,000 per year and earns $1,875 per car he sells. Which equation can be used to find the number
agasfer [191]

Answer:

The equation is, A =30,000 + 1875n.

He sold 9 cars the year he made that amount of money.

Step-by-step explanation:

Before calculating, let's assign letters to certain variables:-

✓ let "A" be used to represent the total amount earned after adding his base salary to the amount he earned as commission per car he sells.

✓ "P" will be used to represent his base salary (a constant = 30,000)

✓ "n" will represent the number of cars sold within a given year.

✓ "B" will be used to represent his commission per car he sells.

Fixing them into a formula, we have:

A = P + n(B)

Since "P" and "B" are constants of 30000 and 1875 respectively, we substitute the letters for their actual amount in the formula:-

A = 30,000 + n(1875)

A = 30,000 + 1875n +This is now the equation that can be used to calculate the number of cars he sold in the year he earned 46,875).

So, since "A" is now $46,875, we substitute accordingly to find the number of cars he sold in the year he earned such amount.

46,875 = 30,000 + 1875b

1875n = 46,875 - 30,000

1875n = 16875

n = 16875/1875

n = 9 cars

Therefore the equation to be used to determine how many cars he sold when he earned $46,875 is:

A = 30,000 + 1875n

He sold 9 cars the year he earned $46,875.

hammer [34]
J = 1 3/7b......J = 10/7b
b = 3 1/2 = 7/2

J = 10/7 (7/2)
J = 70/14 which equals 5

James's height is 5 feet tall........and that is more then 3 1/2 ft
