An advertisement claims that a 5-pound box of detergent will wash 20 loads of laundry. a 5lb box cost 3.50. a 15 lb box cost $10 about how much will you save per load if you buy the 15 lb box

00.50$

Step-by-step explanation:

2×3.50=7+3.50=10.50

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
