The number sentence to describe the cost of the cell phone usage for 6 months and 350 text messages each of those months is $69.99×6 + ($0.05 x 350 x 6) = $524.94 option (b) is correct.
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.
The missing options are:
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
We have:
A cell phone provider charges $69.99 per month for unlimited phone calls plus 5 cents per text message.
The text message cost for 6 months = $0.05x350x6
5 cents = $0.05
Subscription charge = 69.99x6
The total cost can be written as:
$69.99×6 + ($0.05 x 350 x 6) = $524.94
Thus, the number sentence to describe the cost of the cell phone usage for 6 months and 350 text messages each of those months is $69.99×6 + ($0.05 x 350 x 6) = $524.94 option (b) is correct.
