The equation that is described the text is b. $69.99×6 + ($0.05 x 350 x 6) = $524.94. To determine the amount of value of the cell phone usage we can use linear equation.
Linear equation is equations of the first order. The linear equation is explained for lines in the coordinate system.
From the scenario, we know that a cell phone provider charges $69. 99 per month, plus 5 cents per text message. we convert 5 percent, then it will be 0.05. The cell phone is used for 6 months and 350 texts, then to calculate the total cost it can be written as below:
$69.99×6 + ($0.05 x 350 x 6) = $524.94
The option is missing. Here the complete option:
a $69.99 + ($0.05 x 350 x 6) = $174.99
b $69.99×6 + ($0.05 x 350 x 6) = $524.94
c $69.99×6 + ($0.5 x 350 x 6) = $1469.94
d $69.99 + ($0.05 x 350) = $87.49
