Starting Weight

Respuesta :

Answer:

Jacob lost the biggest percentage of his starting weight.

Jacob: 8%

Timothy: 6.4%

Hamza: 7.5%

Formula: (initial weight - new weight)/initial weight times 100.

Step-by-step explanation:

Jacob: 225 pounds - 207 pounds = 12 pounds

x/100 = 12/225

= 1800/225

= 8%

Timothy: 200 pounds - 188 pounds = 12 pounds

x/100 = 12/188

= 1200/188

= 6.4%

Hamza: 280 pounds - 259 pounds = 21 pounds

x/100 = 21/280

= 2100/280

= 7.5%
