(25.45-12.5)+12.45
25.45-12.5
=12.95
12.95+12.45
=25.4 Is your answer
^o^
Ok so,
Let's add the prices for everything together:
4.50 + 3.90 + 1.40 + 1.40 + .90 = $12.10
Now let's subtract the total from how much money have:
15.00 - 12.10 = $2.90
So, they should get $2.90 back
Hope this helps!
Reflection along x-axis is just a swapping of left and right sides. It does not change the size or area of the hexagon.
Hence, the correct option is B.
