Answer:
<h2><em>
D = 3(75) + 30C</em></h2>
Step-by-step explanation:
If a school choir needs to make T Shirts for its 75 members and the printing company charges $3 per shirt, the total amount paid for shirts without coloured printing will be $3 * 75 = 3(75) ... 1
If the printing company charges $50 fee for each color to be printed on shirts, then the total number of colours on the short will cost $30C.... 2
where C is the total amount of colours on all the shirts.
The equation that will represents the relationship between the number of T-shirts orders, the number of colors on shirts and the total cost of the order will be gotten by taking the sum of equation 1 and 2.
<em>The equation needed will be 3(75) + 30C where C is the total amount of colours on all the shirts ordered.</em>
