if y =0.05x + 4.95 per month and x is the number of minutes. If you talk 140 minutes what is the monthly cost.
y =0.05x + 4.95
y = (0.05 * 140) + 4.95
y = ?
thank you.
You're welcome.
To find the monthly cost, we'll substitute the given value of x (140 minutes) into the equation y = 0.05x + 4.95.
Given:
y = 0.05x + 4.95
x = 140 minutes
Substituting x = 140 into the equation:
y = 0.05(140) + 4.95
y = 7 + 4.95
y = 11.95
Therefore, the monthly cost for talking 140 minutes would be $11.95.
