Question

When a band plays at the main stage of a 1,100-person festival, they sell 21 T-shirts. Their next festival gig involves playing on the main stage at a 2,900-person festival. How many T- shirts do they expect to sell? Round your answer to the nearest integer.

Answer 1

Assuming a linear relationship, which may not be the case.

y = mx

For the first festival

21= m(1100)

m = 21/1100

For the second festival

y = m (2900) = (21/1100)(2900) ≈ 55 T-shirts
