Question 181132: I have two story problems
The first one
Shari spent $15.00 on a soccer ball and a kick ball. The soccer ball cost 3 times as much as the kick ball. How much did each ball cost?
I am trying to figure out how to do this problem and I am stumped. Why is this so difficult?
I also have another problem
Baseballs are gong on sale next week for $8.00 each. Mario plans to buy 3 baseballs. He figures he will save a total of $6 if he waits to buy the balls on sale. What is the regular price of a baseball? I think this answer is based on the $24.00 price of the 3 balls and then subtracting the $6.00 from the $24.00 the regular price is $18.00 / 3
is that correct.
Thank you.

Question 181955: . Racquetball. The volume of rubber (in cubic centimeters)
in a hollow rubber ball used in racquetball is given by
V=4/3(pi)R3^3-4/3(pi)r^3
where the inside radius is r centimeters and the outside
radius is R centimeters.
a) Rewrite the formula by factoring the right-hand side
completely.
b) The accompanying graph shows the relationship
between r and V when R =3. Use the graph to
estimate the value of r for which V = 100 cm3.
