Angel bought 8 oranges and 11 apples for a total of $15.22. he knows that each orange coat $0.50 and reasoned that each apple must cost a little more than $1.00. orange costs $0.50 and reasoned that each apple must cost a little more than $1.00. is this guess reasonable? why or why not?

If angel bought 8 oranges, and he knows they are 50 cents, then you can multiply 8 by 0.50 to determine how much he spent only on oranges:
8 x 0.50 = 4.00

Then, you should subtract that value from the total that he spent, to see how much was spent on apples:
15.22 - 4 = 11.22

Finally, because you know Angel bought 11 apples, divide the remaining amount he spent by 11 to determine how much each apple was:
11.22 / 11 = 1.02

So, yes, Angel's guess was reasonable, because $1.02 is, indeed, a little more than $1.00
Hope this helps :)

Sorry Man I need to see the graph
