A bottle and a cork together cost $1.10. The bottle costs $1.00 more than the cork. How much does the cork cost?
If you have not tried to solve it, have a go now. For everyone else, the answer is after the break.
Let’s call the bottle B and the cork C. We know that
B= 1 + C and B+ C=1.10
By substituting B into the 2nd equation, we get:
(1+C) + C= 1.10
so 1 + 2C = 1.10
so the cork costs .05
and the bottle costs 1.05
Did you solve it?
