Elijah spent $5.25 for lunch every day for five School days. He spent $6.75 on Saturday. How much did he spend in all? please help

Elijah spent $33 in all.

Step-by-step explanation:

Multiply 5.25 by 5 to get 26.25, then add 6.75 to that to get 33. Hope this helps :)

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
