Mustafa's soccer team is planning a school dance as a fundraiser. The DJ charges $200 and decorations cost $100. The team decides to charge each student $5.00 to attend the dance. If n represents the number of students attending
the dance, which equation can be used to find the number of students needed to make $1,500 in profit?
O 5n - 300 = 1,500
O5n+ 300 = 1,500
O 5n - 200 + 100n = 1,500
O 5n - 100 - 200n = 1,500

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

step-by-step explanation:

you would need to also lose 1 point for each of the other outcomes for it to be fair.

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
