Question

2. A mobile hotspot is a portable device that provides Wi-Fi.

Each total monthly cost, y, is a fixed fee plus a charge for the
gigabytes of data you use, X.

Answer 1

I would find out how much the monthly cost is and how much gb were used. Afterwards it should be something like this 0’0 and always remember that the x always come first so it would be like this x’y but instead of letters you would add numbers ofc
