jack wants to weigh at most 176 pounds before the baseball season begins. he has already lost 15 pounds. he belives he can lose 1.5 pounds a week. if jack weighed 197 pounds before his weight loss about loss about how many week will it take for jack to get to his desired weight

The answer will be 4 weeks. You know the constant is 1.5 lbs per week and you will multiply that by however many weeks it takes to reach 176

197 - (1.5x) would be your equation and since he's already lost 15 pounds you will include that by subtracting 15 from the equation as well 197 - (1.5 (4)) = 191

191-15=176
