Vanessa wants to purchase a new cell phone plan. the two plans from which she can choose are shown below. vanessa used the system of equations shown below to determine how many minutes she can talk on both plans for the monthly costs to be equal. ca = 22 + 0.13m cb = 44 + 0.09(m –100) when using substitution to solve the system of equations, what is a reasonable solution? when vanessa has used the phone for 775 minutes, the cost for plan a and the cost for plan b will both be $122.75. when vanessa has used the phone for 325 minutes, the cost for plan a and the cost for plan b will both be $64.25. when vanessa has used the phone for 32.5 minutes, the cost for plan a and the cost for plan b will both be $26.23. when vanessa has used the phone for 764 minutes, the cost for plan a and the cost for plan b will both be $121.32.
