Josie selected a number n. she divided n by 2 and then subtracted 0.5 from the result. she took half of that result and then subtracted 0.5 to get the final result of 10. what is the value of n?

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.
