Answer:
y = (4/3)x - 50
Step-by-step explanation:
Step 1 :
Identify the independent and dependent variables.
The independent variable (x) is the square footage of floor space.
The dependent variable (y) is the monthly rent.
Step 2 :
Write the information given in the problem as ordered pairs.
The rent for 600 square feet of floor space is $750 :
(600, 750)
The rent for 900 square feet of floor space is $1150 :
(900, 1150)
Step 3 :
Find the slope.
m = (y₂ - y₁) / (x₂ - x₁)
Substitute (600, 750) for (x₁, y₁) and (900, 1150) for (x₂, y₂).
m = (1150 - 750) / (900 - 600)
m = 400 / 300
m = 4/3
Step 4 :
Find the y-intercept.
Use the slope 4/3 and one of the ordered pairs (600, 750).
Slope-intercept form :
y = mx + b
Plug m = 4/3, x = 600 and y = 750.
750 = (4/3)(600) + b
750 = (4)(200) + b
750 = 800 + b
-50 = b
Step 5 :
Substitute the slope and y-intercept.
Slope-intercept form
y = mx + b
Plug m = 4/3 and b = -50
y = (4/3)x + (-50)
y = (4/3)x - 50
Answer: no
Step-by-step explanation:
4÷5 equals 0.8
While 1 × 1/4 equals 0.25
200 divided by 30 equals 6.66 dishes per minute. It would take 37.55 minutes to do 250 dishes.
Answer:
Step-by-step explanation:
the item costs $ 3
sales tax is 4.4%
how much is the tax....
the tax can be calculated by multiplying the item cost by the percent sales tax ( in decimal form)
turn ur percent to a decimal
4.4% = 0.044
0.044 * 3 = 0.132 rounds to 0.13 <=== sales tax
