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 = t



1. What is the dependent variable (or write "neither" if there is not one)?

Explain why or why not:

y is the dependent variable.

Step-by-step explanation:

Hi, to answer we have to equation given:

3n + 10 = t

Where:

n is the number of yards

t is the total cost of the fabric.  

n is an input value, the independent variable, and y is the output value that depends on the value of n.

For example if he purchases 1 yard of fabric:

t(n) =3n+10

t(1) =3(1) +10

t(1)= 3+10

t=13

t depends on the value of n , so , y is the dependent variable.

Feel free to ask for more if needed or if you did not understand something.

a is the correct

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
