A phone company has a monthly cellular data plan where a customer pays a flat monthly fee and then a certain amount of money per megabyte (MB) of data used on the phone. If a customer uses 96 MB, the monthly cost will be $31.40. If the customer uses 39 MB, the monthly cost will be $22.85. Find a linear equation for the monthly cost of the data plan, C, as a function of x, the number of MB used. C(x) = Use your equation to find the total monthly cost if 260 MB are used.

A phone company has a monthly cellular data plan where a customer pays a flat monthly fee and then a certain amount of money per megabyte (MB) of data used on the phone. If a customer uses $20 \mathrm{MB},$ the monthly cost will be $\$ 11.20 .$ If the customer uses $130 \mathrm{MB}$, the monthly cost will be $\$ 17.80$. a. Find a linear equation for the monthly cost of the data plan as a function of $x$, the number of MB used. b. Interpret the slope and vertical intercept of the equation. c. Use your equation to find the total monthly cost if $250 \mathrm{MB}$ are used.

A phone company has a monthly cellular data plan where a customer pays a flat monthly fee of 10 dollar and then a certain amount of money per megabyte (MB) of data used on the phone. If a customer uses $20$ $\mathrm{MB}$ the monthly cost will be 11.20 dollar. If the customer uses $130 \mathrm{MB},$ the monthly cost will be 17.80 dollar. a. Find a linear equation for the monthly cost of the data plan as a function of $x,$ the number of $\mathrm{MB}$ used. b. Interpret the slope and $y$ -intercept of the equation. c. Use your equation to find the total monthly cost if $250 \mathrm{MB}$ are used.
