Real World Multi Step Equations

1 .   You and your friend are shopping for painting supplies . Your friend wants five bottles of paint and one set of paint brushes . You want seven bottles of paint and two sets of paint brushes . Each bottle of paint costs $ 3.69 . If you and your friend ’s total cost is $ 51.69 , what is the cost of one set of paint brushes ?
a. 5 * 3.69 = 18.45  Friend
b. 7 * 3.69 = 25.83  Me
c. 18.45 + 25.83 = $ 44.28  Total
d. 51.69 – 44.28 = $ 7.41
e. 7.41/3 = 2.47  Paint Brush Price
2 .   In physics the mass energy equivalence is that the mass of a body is measured by its energy content . This may be written algebraically as E=mc2 , where E is energy , m is mass , and c is the speed of light in a vacuum . Transform the equation so that it will be read as a solution for mass , m . Show all the steps .

3 .   The formula to find the surface area of a sphere is to take the radius of the sphere and square it and multiply that amount by pi and then multiply that by 4 . This is written algebraically as S=4πr 2 , where S is the surface area , r is the radius , and the value of π is 3.14 . Rewrite the equation to solve for the radius of the sphere if you know the sphere ’s surface area . Then estimate the radius of a sphere given a surface area of 500 meters 2 .
