Sarah took the advertising department from her company on a round trip to meet with a potential client. Including sarah a total of 17 people took the trip. she was able to purchase coach tickets for $310 and first class tickets for $1080. She used her total budget for airfare for the trip. which was $12200. how many first class tickets did she buy? how many coaches tickets did she buy?

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

step-by-step explanation:

2,160 π

step-by-step explanation:

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
