Percent Change  =(  Change / Initial value  )* 100

Change  = 191,000 - 13,000 = 178,000

Required Percent Increase  = \frac{178,000}{13,000} * 100 = 1369.23  %  = > Approximately = 1,400 %

Answer (D)...

13 to 191 
130 is 1000%
61 is closer to 52 (13*4)
Hence D

Since 13000 becomes 191000, the approximate percentage increase is in excess of 1000%(10 times more)

Only Option D and E remain for careful analysis.
15 times more is 195000(1500%), but we are able to see that the difference, which is 178000 is less then 195000
Hence, we have an answer option which matches (Option D)

ydmuley · Answer

1970 ===> 13,000

1983 ===> 191,000

% Increase  = 191,000 - \frac{13,000}{13,000} * 100

% Increase  = \frac{178000}{130}

% Increase  = \frac{17800}{13}

% Increase  = ~ 1369 
 % Increase = 1400   %

Hence, Answer is D

ScottTargetTestPrep · Answer

We use the percent change formula and substitute the appropriate values:

(New - Old)/Old x 100

(191,000 - 13,000)/13,000 x 100

178,000/13,000 x 100

178/13 x 100 ≈ 1,400%

Answer: D

dabaobao · Answer

Increase = 191k - 13k = 178k

Increase % = 178k * 100/13k = ~1370%

ANSWER = D

ArnauG · Answer

To find the approximate percent increase in the number of coronary-bypass operations from 1970 to 1983, we can use the following formula:

Percent Increase = ((New Value - Old Value) / Old Value) * 100

Let's calculate the percent increase:

Percent Increase = ((191,000 - 13,000) / 13,000) * 100
Percent Increase = (178,000 / 13,000) * 100
Percent Increase ≈ 1,369.23%

Rounding to the nearest whole number, the approximate percent increase is 1,400%.

Therefore, the approximate percent increase in the number of coronary-bypass operations from 1970 to 1983 is option (D), 1,400%.
