Answer: 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.
