+95 Einstein bought 8 oranges and one grapefruit for a total of $4.60. Later that day, he bought six oranges and three grapefruits for a total of $4.80. Write a system of equations. Solve the system of equations to find the price of an orange and grapefruit.
+95 Thanks chill and I understand. For word problems I pretty much just need the set up and then i should be able to figure it out from there. Can you please "set-up" the other word problem i Posted?
+8262 I think that this is it!
Add the prices together.
then, add the oranges only.
Do the same thing with the grapefruit.
Then, divide the number if grapefruits and oranges separately.
i am not sure because I have to log out now! Sorry if it's wrong.
+129840 I'm gong to do the "set-up" but I want YOU to do the solving trQ !!! You have to learn how to do this and I did one earlier for you......
Let x be the price of each orange and y be the price of each grapefruit. So we have....
8x + 1y = 4.60
6x + 3y = 4.80
Hint....think about multiplying the top equation by -3 and adding it to the second equation to "eliminate" y.....!!!
This system has a solution.....don't ask me how I know....I just do !!!!
Let me know if you get stuck and I'll talk you through it...this might seem painful....but you won't learn just by being an "observer"
