Joe's dad was making a patio. he first spread a layer of sand 2.25 inches thick. then he poured a layer of concrete 3.75 inches thick.
what is the total thickness of the sand and concrete combined?
a.
1.50 in.
b.
3.75 in.
c.
5.00 in.
d.
6.00 in.

The answer is D. 6.00 in. because 2.25 plus 3.75 equals 6.

It should be c i think.
