Final answer:
Nigel will take 27 days to sell his box of 35 candy bars.
Step-by-step explanation:
In this problem, Nigel is selling candy bars for his outdoor club. He is averaging 4 bars every 3 days. To find out how many days it will take him to sell his box of 35 candy bars, we can set up a ratio:
Number of days it takes to sell 4 candy bars: 3 days
Number of days it takes to sell 35 candy bars: x days
Using cross multiplication, we can find x:
4 * x = 3 * 35
x = (3 * 35) / 4
x = 26.25
Since we need to round up to the next whole number, Nigel will take 27 days to sell his box of 35 candy bars.
