teemu's t-shirts designs and manufactures t-shirts for a $15 flat design rate and $7.50 for each t-shirt.he wants to sell his t-shirts to the senior class for their graduation party. he is going to charge them $10 for each t-shirt.
a) write a function,c, representing the cost of,t,t-shirts.
b) write a function,I, representing the income that teemu will generate from the sale.
a) The cost of t-shirts can be represented by the following function:
c(t) = (15 + 7.50*t)
Where t is the number of t-shirts.
b) The income generated from the sale can be represented by the following function:
I(t) = (10*t - c(t))
Where t is the number of t-shirts and c(t) is the cost of t-shirts as calculated in the previous function.
a) To calculate the cost of t-shirts, we need to consider the flat design rate and the cost per t-shirt. The formula to calculate the cost is as follows:
Cost = (Flat Design Rate) + (Number of T-shirts * Cost per T-shirt)
In this case, the flat design rate is $15, and the cost per t-shirt is $7.50. Let's write the function C(t) where t represents the number of t-shirts:
C(t) = 15 + (7.50 * t)
b) To calculate the income generated from the sale of t-shirts, we need to multiply the selling price per t-shirt by the number of t-shirts. The formula is as follows:
Income = Selling Price per T-shirt * Number of T-shirts
Here, Teemu has decided to charge $10 per t-shirt. Let's write the function I(t) where t represents the number of t-shirts:
I(t) = 10 * t
