Answer:

well she can count up the average amount of tables, and the average amount of students in the school, later determine how many kids sit at the tables, for example, if there's five tables, and in each table there are five students, round those up and you have 25 students, only Amanda's answer would be much higher depending on the school and cafeteria

Please solve with explanation will give BRAINLIEST and Bonus Points
erastova [34]

Let d = # of dimes

Let q = # of quarters

equation #1: number of coins

    d + q = 1234

equation #2: value of coins

    0.10d + 0.25q = 290.05

Solve #1 for d:

    d=1234-q

Sub #1 into #2 and solve for q:

    0.10d + 0.25q = 290.05

    0.10(1234-q) + 0.25q = 290.05

    123.4 - 0.10q + 0.25q = 290.05

    0.15q =  166.65

    q = 1111

Now go back to d=1234-q and sub in 1111 for q to find d:

    d = 1234 - 1111

    d = 123

1111 quarters and 123 dimes.
