Question

8. Mrs. Harper bought snacks for her class. She has 28 students. She bought Sour Patch Kids for $1.50 each and Takis for $1.25 each. She spent a total of $38.25. Circle all that are true: She bought 13 Takis She bought 13 Sour Patch Kids She bought the same number of each snack She bought more Takis then Sour Patch Kids She bought all Takis and no Sour Patch Kids She bought 15 of each snack​

Answer 1

Since Mrs. Harper spent a total of $38.25, the cost of all the snacks she bought is $38.25. We can write this as the total cost of Takis plus the total cost of Sour Patch Kids, or $1.25 * t + $1.50 * s = $38.25, where t is the number of Takis and s is the number of Sour Patch Kids.

Mrs. Harper has 28 students, so if she bought the same number of each snack, she would have bought 28 / 2 = <<28/2=14>>14 of each snack. Plugging in 14 for both t and s in the equation above, we get $1.25 * 14 + $1.50 * 14 = $38.25, which means that the total cost of the snacks was $38.25. Since the total cost of the snacks was $38.25 and Mrs. Harper spent $38.25 on snacks, this means that she bought 14 of each snack.

Therefore, the statements that are true are "She bought the same number of each snack" and "She bought 15 of each snack." The other statements are not necessarily true.
