A pool company has learned that, by pricing a newly released noodle at $4, sales will reach 15,000 noodles per day during the summer. Raising the price to $6 will cause the sales to fall to 13,000 noodles per day.
[Hint: The line must pass through (4,15000) and (6,13000).]
a. Assume that the relationship between sales price and number of noodles sold is linear and write an
equation describing this relationship.
y=
b. Predict the daily sales of noodles if the price is $4.50.
y=noodles
