Question

Jack will spend a total of exactly $15 on Redbix movies and games. What equation in standard form can he use to graoh a line showing the different amounts of movies at $1.25 and games at $2.50 he can buy

Answer 1

`1.25x+2.5y -15 = 0`

Explanation:

Total amount to be spent on Redbix movies and games = $15

Money to be paid for each movie = $1.25

Money to be paid for each game = $2.50

To find:

Equation in standard form that can be used to graph the line.

Solution:

First of all, let us learn about the standard form of equation of a line.

Standard form can be represented as:

`Ax+By+C =0`

Where
`A,B, C` are constants.

Now, let us try to make equation.

Let number of movies bought =
`x`

Amount to be paid for movies = $1.25
`x`

Let number of movies bought =
`y`

Amount to be paid for movies = $2.50
`y`

Total money is $15.

Therefore, we can write the equation as:

`1.25x+2.5y = 15`

Standard form can be written as:

`1.25x+2.5y -15 = 0`
