Jaden discovers another prepaid phone plan (Plan B) that charges a flat fee of $15 per month, then $.05 per text sent or minute used.
Write an equation for the cost of Plan B.
did that -- you ignored it.
To write an equation for the cost of Plan B, we need to consider the fixed monthly fee and the variable charges for texts and minutes used.
Let:
x = number of texts sent
y = number of minutes used
The cost of Plan B includes both the fixed monthly fee of $15 and the charges for texts and minutes used. Given that the cost per text or minute is $0.05, we can write the equation as:
Cost of Plan B = Fixed Monthly Fee + (Cost per text × Number of texts sent) + (Cost per minute × Number of minutes used)
Substituting the given values, we have:
Cost of Plan B = $15 + ($0.05 × x) + ($0.05 × y)
So the equation for the cost of Plan B is:
Cost of Plan B = $15 + $0.05x + $0.05y
