PLEASE HELP :( I HATE SCHOOL
A cell phone battery charges at a rate of 16% every thirty minutes. When initially plugged into the charger, a cell phone has 10% battery.

Write an equation relating the amount of time, measured in hours, it takes to charge a cell phone as a function of the battery charge.
Use complete sentences to describe the rate in which the battery charges in terms of the time that it is charging.

100= 10+ 16t

Step-by-step explanation:

If beginning at 10 percent you initially are only in need for 90% charge. Earning 16% every thirty minutes you can initially do x4 for two hours on the charger and know you aren't at 100 yet. (16x4)+10= 64+10= 74. 100-74= 26. You need one more hour (total of 6 half hours) on the charger.

Another way of doing it could be 16÷90 and getting 5.blahblahblah and rounding up.
