Please help! I will mark as brainliest. <3

Answer(s):

1. $5000

2. 100x

3a. at least

3b. 9 meals

My shown work:

1. $100 per meal. Monthly expenses are $3100.

50 meal [$100 x 50 = x]

x = $5000

2. x = number of meals sold

Inequality (y=mx+b)

Giving me: 900 = 100x

100 x 9 = 900

40 is the final : )

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
