Each light bulb at hotel california is either incandescent or fluorescent. at a certain moment, forty percent of the incandescent bulbs are switched on, and ninety percent of the fluorescent bulbs are switched on. if eighty percent of all the bulbs are switched on at this moment, what percent of the bulbs that are switched on are incandescent? a. 22 (2/9)%b. 16 (2/3)%c. 11 (1/9)%d. 10%e. 5%

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
