Step-by-step explanation:
Answer:
What are the choices under "select"? Without them, I'm just guessing.
Money can't be expressed as less than 1 cent, or $0.01
The actual range is the set of all (real numbers/non-negative numbers/ numbers <u>></u> 320 (?)) up to the hundredths place.
Answer: you spent 250 hours during your cleanup.
you spent 150 hours painting
Step-by-step explanation:
Let x represent the number of hours that you spent during your cleanup.
Let y represent the number of hours that you spent painting.
you earn $8 an hour cleaning up and $12 an hour painting last summer and you earned $3800 . it means that
8x + 12y = 3800- - - - - - - - - -- 1
You worked a total of 400 hours. This means that
x + y = 400
Substituting x = 400 - y into equation 1, it becomes
8(400 - y) + 12y = 3800
3200 - 8y + 12y = 3800
- 8y + 12y = 3800 - 3200
4y = 600
y = 600/4 = 150 hours
Substituting y = 150 into x = 400 - y, it becomes
x = 400 - 150
x = 250 hours
Take two points to find the slope
Let;s take (1, -3) and (-3, -1)
Point slope formula is
m =
or
y₂-y₁ = m×(x₂-x₁) Which is the same thing
m =
=
It can be simplified:
=
Now we found the slope
Same formula:
y₂-y₁ = m × (x₂-x₁)
Substitute the point only (1, -3)
y₂-(-3) =
× (x₂-1)
y₂ + 3 =
× (x₂ - 1) (minus minus = plus)
The last option is the answer
If you multiply $8.00 by 6.35% the answer is .508. Round that up to .51. So tax is .51. You add that to $8.00 for a total amount of $8.51.
