Given the statement:

Ben bought 3 oranges for 89 cents each and 4 apples for x dollars each. He spent $7.15 for the apples and oranges.

Solution:

Based on the given statement, we can solve the cost for the number of apples by representing first the equation.

7.15 = (3)(.89) + 4x

7.15 = 2.67 + 4x

x = apple cost

Transpose 2.69 to the other side of the equation hence it must be taken to note that in transposing a number, the sign changes.

4x = 7.15 - 2.67

4x = 4.48

Divide both sides by 4 in order to determine the value of x.

4x/4 = 4.48/4

x = $1.12

Final answer:

Each apple cost $1.12
