A certain business is marketing its product and has determined that, when it raised the selling price of its
product, its sales went down. The number of units
sold, P, is modeled by the equation P=1200-20s,
where s is the selling price, in dollars. Based on this
model, what is the decrease in selling price from 700
units sold to 900 units sold?
a) 5
b) 10

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.

step-by-step explanation:

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
