NEED HELP ASAP...You must show all your work and answer the questions in complete sentences!My niece wanted to create a coverup she saw on Pinterest. It required a square piece of patterned fabric. We found an online store with some bright and fun samples of fabric at a reasonable price. They charge a flat shipping fee of $10 and then $3 per yard.The formula 3n + 10 = t can be used to determine the total cost of the fabric, where n is the number of yards purchased, and t is the total cost of the fabric.3n + 10 = t1. What is the dependent variable (or write “neither” if there is not one)? _______________Explain why or why not:_____________________________________________________________________________________________________________________________________________________________________2. Since all squares are similar, then the ratio of one square’s side to perimeter is proportional to any other’s. If the side of a square of fabric is 2 yards, then the perimeter is 8 yards. Use a proportion to determine the perimeter of a square with a side 9 yards long. Write your final answer in a complete sentence.
