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
