The cost of renting a car is $46/week plus $0.25/mile traveled during that week. An equation to represent the cost would be y=46
julsineya [31]

The answer for part a is $60.25, for part b the answer is 76 miles, and for part c the answer is 216 miles.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The equation to represent the cost would be y=46+0.25x

x is the number of miles.

a) What is your cost if you travel 57 miles?

Plug x = 57 in the above equation:

y = 46 + 0.25(57)

y = $60.25

b) If your cost was $65.00, how many miles were you charged for traveling?

Plug y = 65 in the equation:

65 = 46 + 0.25x

x = 76 miles

c) Suppose you have a maximum of $100 to spend for the car rental. What would be the maximum number of miles you could travel?

Plug y = 100 in the equation:

100 = 46 + 0.25x

x = 216 miles

Thus, the answer for part a is $60.25, for part b the answer is 76 miles, and for part c the answer is 216 miles.

What is the sales tax on a breakfast order that totals $10.50 when tax is 5%
Alecsey [184]
First, you would need to create an equation for this problem. Let x represent the unknown tax. 
\frac{x}{10.50} = \frac{5}{100}

Next, you would cross multiply. 
100x = 52.5

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 100. 
x = $0.525

I hope this helps!
