If there is 10% of $18 = 18 x 0.9 (1 - 0.1) = $16.20
Therefore the pie costs $16.20
He is saving 18 - 16.20 = $1.80
Answer:
f(x) = 2m + 30
Step-by-step explanation:
Since the truck costs 30 dollars to rent plus the 2 dollars per mile to find the function rule you use an equation that makes the 2 dollars per mile the dependent variable.
The correct answer is 4.8 hours
Explanation:
This mathematical problem can be solved by using the rule of three, which involves finding an unknown value by using three related values. The process is shown below:
1. It is known a fully charged battery (100% battery) lasts 16 hours. This can be represented as 100 = 16. But it is not know how much a 30% battery last; this can be represented as 30 = x.
2. Write all the values
100 = 16
30 = x
3. Cross multiply to create an equation and solve the equation
100 x = 48
x = 480 / 100
x = 4.8
Answer: 11.2$
Step-by-step explanation:
Answer:
3x-2y
Step-by-step explanation:
log10^(3x-2y)
We know the base is base 10 since it is not written
log10 10^(3x-2y)
The log10 10 cancels
3x-2y
