I have a word problem that I need help with.?

Question

The electricity costs of a business increased from $18,000 one year to $19,000 the next. To the nearest whole percent, what was the rate of increase?

Answer 1

the increase equals $19,000 - $18,000 = $1,000 / year
But the rate of increase equals the $1,000 / $18,000
The percentage equals 100 * 1000/18000 = 5.5555%
Round to 6%

Answer 2

Note that the actual increase is $1,000. (19,000-18,000). So the rate of increase is the increase divided by the initial cost, that is, the first year, then multiply by 100 to get the % value.

Or, 1,000/(18,000) x 100 = % or equal to 5.55% or to the nearest whole percent the final answer is 6%.

Answer 3

1000/18000=1/18= 5.5555555 % . So the nearest integer is 6%.

Answer 4

5%

Answer 5

105.5%
