Final answer:
Allie has $20 and each person's bowling cost, including shoe rental and three games, is $7. Dividing the total budget by the cost per person indicates Allie can bring only 1 friend bowling, which is not among the provided options A, B, C, or D.
Step-by-step explanation:
The question asks how many friends Allie can bring bowling given her budget constraints. To solve this, we need to calculate the total cost for Allie and her friends to play three games each, including the shoe rental cost for each person.
Allie's total budget is $20. The shoe rental cost is $4 per person. The cost to play three games is $3 per person ($1 per game). Therefore, the total cost per person is $4 for shoe rental plus $3 for the games, which is $7.
We need to determine how many people can bowl (including Allie) for $20. We divide Allie's budget by the total cost per person:
$20 ÷ $7 = 2.857
Since we cannot have a fraction of a person, we round down to 2 people. This count includes Allie, so she can bring 1 friend.
However, this answer is not one of the provided options. Since Allie is included in the count, it is possible that the question meant to ask about additional friends besides Allie. In that case, we need to subtract Allie's cost first and then divide the remaining budget by the cost per friend:
$20 (Allie's budget) - $7 (Allie's personal cost) = $13
Now, we divide the remaining budget by the cost per friend:
$13 ÷ $7 = 1.857
Once again, rounding down to the nearest whole number, we get that Allie can bring 1 friend. Even when Allie's cost is subtracted first, she can only afford to bring 1 friend bowling given the provided options. Therefore, none of the provided options (A, B, C, D) are correct.
