Under her cell phone plan, Sadie pays a flat cost of $61.50 per month and $4 per gigabyte. She wants to keep her bill at $75.50 per month. Write and solve an equation which can be used to determine gg, the number of gigabytes of data Sadie can use while staying within her budget.

Respuesta :

The equation that can be used to find the number of gigabytes of data Sadie can use is 61.50 + 4n = 75.50 and the number of gigabytes is 3.5 GG.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Sadie pays a flat cost of $61.50 per month and $4 per gigabyte. She wants to keep her bill at $75.50 per month.

Let Sadie use n number of gigabytes of data :

The equation can be framed:

61.50 + 4n = 75.50

4n = 75.50 - 61.50

4n = 14

n = 14/4

n = 7/2

n = 3.5 GG

Thus, the equation that can be used to find the number of gigabytes of data Sadie can use is 61.50 + 4n = 75.50 and the number of gigabytes is 3.5 GG.
