Six pears and three apples cost $3.90. Two pears and five apples cost $3.30. How much does one pear cost?
Hint: You have two unknowns (variables), so you need two equations. Write one equation for each situation and solve the system of equations.
(1): Six pears and three apples cost $3.90
(2): Two pears and five apples cost $3.30
(1) - 3*(2):
three apples - 15 apples cost $3.90 - 3*$3.30 --->
12 apples costs $6 -->
The apple costs $0.50
The pear costs $0.40
thanks!can you help me with my other one??
