Alex weighs 185 pounds. If he decreases his weight by 10% what will be his new weight?

Given the conditions, Alex's new weight would be:

166.5 pounds.

Step-by-step explanation:

In terms of percentage, you should consider that Alex's initial weight is 100% when mentioning that he loses 10% of his initial weight, you must perform subtraction of percentages to obtain the new percentage of his initial weight:

Alex's Current Weight Percentage = 100% - 10% = 90%

Now you just have to multiply the initial weight by his new percentage and you will get Alex's new weight in pounds:

Alex's current weight = 185 pounds * 90% Alex's current weight = 166.5 pounds.

Answer:His new weight will be 167 pounds

Step-by-step explanation:

185 - 10% (18.5) = 166.5 rounds up to 167
