A local cell phone company offers two different calling plans. In the first plan, you pay a monthly fee of $30 and $.35 per minute. In the second plan you pay a monthly fee of $99 and $.05 per minute. <span>a. write a system of equations showing the two calling plans. </span> <span>scheme 1: monthly charges: 30 + 0.35m .....m = total minutes during the month </span> <span>scheme 2: monthly charges: 99 + 0.05m </span>
<span>b. when is it better to use the first plan </span> <span>When you make few calls, only where unavoidable. </span>
<span>c. when is it better to use the second plan. </span> <span>When you make a lot of call, literally "always on hello!" </span>
<span>d. how much does it cost when the calling plans are equal? Question is unclear for me . </span>
