S A band is selling concert shirts on their website. If they charge $15 a shirt, they sell 550 shirts in one month.
The monthly cost for the shirts is $1500. The band manager estimates that for every $2 increase in price they
will sell 20 less shirts a month. The monthly profit for the band selling shirts can be modeled with the equation
P(x)=(15+2x)(550 – 20x) –1500, where x represents the number of $2 price increases. Use technology to
graph the profit equation and determine the number of shirts the band needs to see in a month to maximize
their profits.

Sorry I dont know the answer.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
