A music company is introducing a new line of acoustic guitars next quarter. These are the cost and revenue functions, where x represents the number of guitars to be manufactured and sold. r(x)=120x
c(x)= 100x + 1840
the company needs to sell at least guitars for a total revenue of $ to start making a profit.

step-by-step explanation:

35-60 students are taking math.

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

here try this one

3a-24=0

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.
