The formula for percent error is: (M-A)/A x 100
M= the amount of the sample measured
A= the exact value of the sample
And the value of M-A is always positive
So, 2.75-2.699= .051g/cm3, and .051/2.699=.01889
.01889 x 100=1.889% or 1.9% error

Answer:
y = 40 + 2x.
Step-by-step explanation:
To become a member of the library-all-star-members club, we have to invest $40 for a sign-up fee and a $2 monthly fee.
If we consider x months membership is required and the total cost for that is y.
Then we can model the situation with an equation in slope-intercept form as
y = 40 + 2x. ( Answer )
