    Multiple choice

    Hi

    can anyone help me with the problem below?


    The total cost for five items of repair work on a car was $195. Overhaul of the carburetor cost twice as much as the tune-up, brake pads cost one-third as much as the carburetor overhaul, and alignment and wheel balancing each cost one-third as much as the tune-up. What did the tune-up cost?

    A. $30
    B. $45
    C. $60
    D. $90
    E. One cannot tell from the information given.

    let $\displaystyle x$ be the cost of the tuneup.

    then the cost of the carburetor overhaul is $\displaystyle 2x$

    the cost of the brake pads is $\displaystyle \frac 13 (2x)$

    the costs of alignment and wheel balancing are $\displaystyle \frac 13x$ each.

    sum all these, equate to 195 and solve for x

    Here's what you do:

    When you are given a problem like this you need to read the whole question and see how much information you are given. What is given in this problem is:

    Total Cost = 195
    Overhaul of the carburetor = 2*tune-up
    brake pads = (1/3)*Overhaul of the carburetor=(1/3)*2*tune-up
    alignment = (1/3)*tune-up
    wheel balancing = (1/3)*tune-up


    Now you can take this information and add them together because they all have the same variable in them (i.e. tune-up) and set them equal to 195. So you get:

    2*tune-up+(1/3)*2*tune-up+(1/3)*tune-up+(1/3)*tune-up=195

    The answer you get is how much your tune-up cost.

    Hope this helps!
