1. when the fundraiser began, 600 people wanted to purchase the dance troupe’s t-shirts at $12 per t-shirt, but as the group increased the price of their t-shirts, they noticed a fall in the demand. for every $1 increase in price, the demand fell by 50 shirts. the dance troupe’s initial supply was short by 210 t-shirts which corresponded to an initial price of $9.75. for every $1 increase in price, they ordered 40 more t-shirts. write a system of linear equations to represent both the demand and supply for the t-shirts. let q represent the quantity of t-shirts and p represent the price.

Let q represent the quantity of T-shirts and $p represent the price

For demand, q=600 when p=$12

For every $1 increase in price, the demand fell by 50 shirts

600 - q = 50*(p-12)

600 - q = 50p - 600

q = 1200 - 50p

For supply, q=210 when p=9.75

For every $1 increase in price, they ordered 40 more T-shirts.

q - 210 = 40*(p-9.75)

q = 40p - 170

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
