11. A person’s 3-point field goal percentage is determined by dividing the number of 3-point field goals made by
the number of 3-point field goals attempted. Eric has made 12 out of 32 3-pointers and has a 3-point field goal
percentage of 37.5%.
a. He wants to have a 3-point field goal percentage of 50%. Write an equation that can be used to determine x,
the number of 3-pointers he has to make in a row to have a 3-point field goal percentage of 50%?
b. How many 3 pointers will Eric have to make?
12. A chemistry teacher has 10 liters of 47% hydrochloric acid. She wants to add water to dilute the solution to be
