From ETS Paper test
A certain fruit stand sold apples for $0.70 each and bananas for $0.50 each. If a customer purchased both apples and bananas from the stand for a total of $6.30, what total number of apples and bananas did the customer purchase?
What is the fastest way to solve this? I used trial and error.
I took the largest value, cost of apples, and multiplied it by 9 = $6.30. This is the largest number of apples the person could have bought. However, since this person bought both apples and bananas, i kept going.
Then checked 8 apples ($5.60) which leaves $0.70 for bananas. Can't be the right amount since it doesn't divide evenly.
Did trial and error, until I got down to 4 apples ($2.80) which left $3.50 for apples. Works.
