Math Problem Statement

Last year, Pinwheel Industries introduced a new toy. It cost $5200 to develop the toy and $10 to manufacture each toy. Fill in the blanks below as appropriate.

A.) Give a linear equation in the form C=mn+b that gives the total cost, C, to produce n of these toys: C=  

B.) The total cost to produce n=1350 toys is $.

C.) With $36700, a total of  toys can be produced.

Solution

We are given the following details:

  • The development cost is a fixed cost of $5200.
  • Each toy costs $10 to manufacture.
  • nn represents the number of toys produced.

A.) Linear equation for total cost

The total cost CC includes the fixed cost of $5200 and the variable cost of $10 per toy. Thus, the linear equation in the form C=mn+bC = mn + b is:

C=10n+5200C = 10n + 5200

B.) Total cost to produce 1350 toys

Substitute n=1350n = 1350 into the equation C=10n+5200C = 10n + 5200:

C=10(1350)+5200=13500+5200=18700C = 10(1350) + 5200 = 13500 + 5200 = 18700

So, the total cost to produce 1350 toys is $18,700.

C.) Number of toys that can be produced with $36,700

We are given that the total cost is $36,700. Use the equation C=10n+5200C = 10n + 5200, and set C=36700C = 36700:

36700=10n+520036700 = 10n + 5200

Solve for nn:

367005200=10n36700 - 5200 = 10n 31500=10n31500 = 10n n=3150010=3150n = \frac{31500}{10} = 3150

So, 3150 toys can be produced with $36,700.


Do you want further details or have any questions? Here are some related questions to explore:

  1. What if the fixed cost increased to $6000? How would the equation change?
  2. How would the cost equation change if it costs $12 to manufacture each toy?
  3. How many toys can be produced with $50,000?
  4. If 500 toys were produced, what would the total cost be?
  5. How does the number of toys produced affect the total cost?

Tip: When working with linear cost functions, the fixed cost is the y-intercept, and the per-unit cost is the slope.
