Things we know: every pound of cherries cost four dollars.

We don't know how much the mother got and it is represented by the variable 'r'. But we do know how many pounds the dad got. He got two pounds.

We know the total cost the mom had to pay which is 4 * r and the amount the dad paid is 4 * 2 or 8.

Now we want to make an algebraic expression that represents how much more the mother paid than the father.

Final answer:

8 - (4 * r)

Hope this helps!

A division of the Gibson Corporation manufactures bicycle pumps. Each pump sells for $10, and the variable cost of producing eac
svlad2 [7]

Answer:

12,500 units

Step-by-step explanation:

Given:

Selling cost of the pump = $10

Variable cost of producing each unit = 60% of selling cost

or

Variable cost of producing each unit  = 0.60 × $10 = $6

Monthly fixed cost = $50,000

Now,

The profit per unit = Selling cost - Variable cost

or

The profit per unit = $10 - $6 = $4

Therefore,

The breakeven point = \frac{\textup{Fixed cost}}{\textup{Profit per unit}}

or

the breakeven point = \frac{\textup{50,000}}{\textup{4}}

or

the breakeven point = 12,500 units
