Brian has reduced his cholesterol level by 19% after his last check up. If his original level was 180, what is his approximate cholesterol level now?
To find Brian's approximate cholesterol level now, we need to calculate the 19% reduction and subtract it from his original level. Here's how you can do it:
1. Convert the percentage reduction to a decimal number. Divide 19 by 100: 19 ÷ 100 = 0.19.
2. Multiply the original cholesterol level by the decimal reduction to calculate the amount of reduction. Multiply 180 by 0.19: 180 × 0.19 = 34.2.
3. Subtract the reduction amount from the original cholesterol level to find the approximate current cholesterol level. Subtract 34.2 from 180: 180 - 34.2 = 145.8.
Brian's approximate cholesterol level now is 145.8.
