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:
![m=\frac{y_2-y_1}{x_2-x_1}\\\\=\frac{90-70}{2-1}\\\\=\frac{20}{1}=20](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5C%5C%5C%3D%5Cfrac%7B90-70%7D%7B2-1%7D%5C%5C%5C%5C%3D%5Cfrac%7B20%7D%7B1%7D%3D20)
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.
This is 4/5 orange juice and 1/5 water. this means there is 4 times as much orange juice as there is water as 4/5 = 4 * (1/5)
this means that if there is one litre of water then there is four times this of orange juice.
