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
