Question

Sean gets 15 stars every week for completing his chores. For every 5 stars, he earns $1. If he wants enough money to go see a movie for $15, how many weeks does he need to work? A. 5 B. 3 C. 7 D. ||​

Answer 1

Explanation:

To determine the number of weeks Sean needs to work to earn enough money to go see a movie for $15, we can set up an equation based on the given information.

Sean earns 15 stars every week and for every 5 stars, he earns $1. Therefore, the amount of money he earns in a week can be calculated by dividing the number of stars by 5 and multiplying it by $1:

Money earned in a week = (Number of stars / 5) * $1

To earn $15, Sean needs to work for a certain number of weeks. We can set up the equation as follows:

Money earned in n weeks = $15

(15 stars/week) * (Number of weeks / 5 stars) * $1 = $15

By simplifying the equation, we can solve for the number of weeks:

3 * Number of weeks = 15

Dividing both sides of the equation by 3, we find:

Number of weeks = 15 / 3

Number of weeks = 5

Therefore, Sean needs to work for 5 weeks to earn enough money to go see a movie for $15.

The correct answer is A. 5 weeks.
