Answer:

349

Step-by-step explanation:

We know that a₁ (the first term) is 6 and d (the common difference) is 13 - 6 = 7.

Explicit formula: aₙ = a₁ + (n - 1)d = 13 + (n - 1) * 7 = 7n - 1

Therefore, a₅₀ = 7(50) - 1 = 349

Mustafa’s soccer team is planning a school dance as a fundraiser. The DJ charges $200 and decorations cost $100. The team decide
Aleksandr [31]

DJ + decorations = 200+100 = 300

tickets are $5 each

 so 5n would be the total amount of money made then you need to subtract 300 ( cost of DJ and decorations )

 so answer is: 5n - 300 = 1500

if you want to solve:

5n -300 = 1533

add 300 to each side

5n = 1800

divide both sides by 5

1800/5 = 360 tickets need to be sold
