Question

A cellular phone company uses the formula $16+ $0.04m to calculate each subscriber's monthly

bill, where m is the number of minutes used. If Angelo uses 142 minutes on his phone this month,
how much will his bill be?

Answer 1

The formula for calculating Angelo's monthly bill is $16 + 0.04m$, where m is the number of minutes used. Since Angelo used 142 minutes, we substitute that value into the formula:

$16 + 0.04 * 142 = 16 + 5.68 = 21.68$

So Angelo's monthly bill will be $21.68.
