    If you had to estimate/round up the dog's weight, the best answer would be C. 50+100+100=t. t would then equal 250, when the true answer is 243 lbs.

    88+107+48=243 which is close to 250. 88 is close to 100. 107 is close to 100. 48 is close to 50. 100+100+50 is close to the real answer, so C is correct.
