Twelve more than half of a number is equal to the number
tester [92]
Let's consider that number to be 'x'..
So, twice the number (2x) is 12 greater than than the half of the number.
So the equation will be like,
2x=12+x/2
Solving this further,
2x=(24+x)/2
=> 4x=24+x
=>4x-x=24
=>3x=24
=>x=8..
So the number is "8".

Hi there! The answer is $98

When something becomes 0% more expensive it means that the prices have remained the same as the price last year. Since the price last year was $98, the price this year is also $98.
