Matthew needs $3,600 to buy a used car. He has already
saved $2,130. He earns $24.50 per hour working as a Math
tutor. How many hours does he need to work at his job in
order to buy the car?

60 hours

Step-by-step explanation:

$3,600 - $2,130 = $1,470 (how much he needs to make)

$1,470 divided by $24.50 = 60 hours

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
