QUESTION 1
There is a linear relationship between the price a shop charges for a product and the quantity of that product that will sell at that
price. If the shop charges $25 for a t-shirt, they will sell 150 of them that week. If the shop charges $18 for a t-shirt, they will sell
220 of them that week.
Write an equation that models the linear relationship described above.
DO NOT USE ANY SPACES between variables, constants, equals signs, and operation signs.
For example, DO NOT enter y = 2x + 1.
DO ENTER:
y=2x+1.
Put parentheses around constants that are fractions like this: y=(2/3)x-(1/2)
To write your equation, use the variables:
p= price of a t-shirt ($)
q= the quantity (number of) shirts that will sell in a week at that price
The equation in slope-intercept form is
7.
