Anna went to the grocery store. She bought 3 oranges and 6 apples. She paid $4.50. Maria went to the same store and bought 2 oranges and 2 apples. Her cost was $2.10. How much would one apple cost?

Question

ivettef365 · Answer

x = oranges
y = apples

so you have the following equations

3x + 6y = 4.50
2x + 2y = 2.10

ivettef365 · Answer

can you solve the system of equation

anonymous · Answer

no

ivettef365 · Answer

now you can add as follows:

 3x + 6y = 4.50
-6x - 6y  =-6.30
============
-3x         = -1.80

ivettef365 · Answer

now divide by -3 and you have

  x = .60   so the oranges cost 0.60, find how much the apples cost

ivettef365 · Answer

do you know how to ?

ivettef365 · Answer

substitute the x = .60 on the equation so you have

3 (.60) + 6y =  4.50
