Step-by-step explanation:
Answer:
y = 16x + 6
Step-by-step explanation:
They charge $14 for each DVD, which mean the slope of the function is 14
You must pay an additional $6 for shipping and handling, which means no matter how many DVD you buy, you have to pay a flat fee for $6
So our function is:
y = 16x + 6 where:
y is total cost
x is the number of DVD you buy (x>0)
5/8 9/x
Cross multiply
9x8=72
5×x=5x
Rewrite the equation
72 = 5x
Divide by 5
72÷5=14.4
So, x=14.4
