Answer:
$20 per day with a $50 fee
Step-by-step explanation:
For 1 day, the gold fee is $70. For 2 days, the gold fee is $90. This can be written as the ordered pairs (1, 70) and (2, 90).
To find the daily fee, we will find the slope between the points:
Next we will use point-slope form:
y-y₁ = m(x-x₁)
y-70 = 20(x-1)
Use the distributive property:
y-70 = 20(x)-20(1)
y-70 = 20x-20
Add 70 to each side:
y-70+70 = 20x-20+70
y = 20x+50
This means the fee is $50.
Answer:
k = - 4
Step-by-step explanation:
The equation that represents direct proportion is
y = kx ← k is the constant of proportion
To find k use any ordered pair from the table.
Using (2, - 8 ) , then
- 8 = 2k ( divide both sides by 2 )
k = - 4
The answer is 3/4 and it was already simplified
Answer:
46.80
Step-by-step explanation:
because 45/4%=1.80 and 45+1.80=46.80
