Question

john is trying to raise money for a trip he is taking. he is selling t-shirts for $10 each and bracelets for $6 each. he must at lease $90 to be able to go on his trip. he knows he can sell at least 7 bracelets.

Answer 1

John needs to sell at least 7 bracelets and 5 t-shirts to meet the minimum amount required for his trip.

Step-by-step explanation:

To calculate the minimum amount of money that John needs to raise for his trip, we need to determine the total cost of the t-shirts and bracelets he plans to sell. He sells t-shirts for $10 each and bracelets for $6 each. We know that he can sell at least 7 bracelets. So, the minimum amount of money he can raise from selling bracelets is $6 multiplied by 7 which is $42. We need to find the remaining amount by subtracting $42 from the total amount needed for the trip, which is $90. Therefore, John needs to raise an additional $90 - $42 = $48 from selling t-shirts.

Next, let's find the number of t-shirts John needs to sell. Since he needs to raise $48 from selling t-shirts and each t-shirt is priced at $10, we can divide $48 by $10 to find the minimum number of t-shirts John needs to sell. The quotient is 4.8, but since you cannot sell a fraction of a t-shirt, John needs to sell at least 5 t-shirts.

In summary, in order to meet the minimum amount required for his trip, John needs to sell at least 7 bracelets and 5 t-shirts.
