Question

Brock wants to compete for the featherweight boxing title, but the upper limit for that weight class is 126 pounds. He currently weighs 134 pounds. Brock can lose 3 pounds per day if he does vigorous workouts. The number of days, d, that Brock will need to work out to compete at the featherweight level is represented by the inequality 134 – 3d < 126. Select the fewest number of days he would have to work out to compete at the featherweight level.

Answer 1

Answer:

We can say that Brock needs to workout for minimum 3 days to compete at feather weight level.

Step-by-step explanation:

Given:

Current Weight of Brock = 134 pound

Weight Brock need for feather weight boxing title =126 pounds.

Wight loss per day = $3

Number of days to reduce = 'd'

The inequality representing the number of days of workout is given by;

$134-3d>126$

We need to find the fewest number of days of work out.

Solving the above Inequality we get;

We will first Subtract both side by 134 using Subtraction property of Inequality.

$134-3d-134>126-134\\\\-3d>-8$

Now by dividing Both side by -3 using Division property of inequality we get;

$\frac{-3d}{-3}<\frac{-8}{-3}\\\\d>2.67$

Hence We can say that Brock needs to workout for minimum 3 days to compete at feather weight level.

Answer 2

Answer:

C. 3

Step-by-step explanation:

Brock weighs 134 pounds, he will lose 3 pounds a day until he is 126 pounds

D will represent the number of days he will work out.

134 - 3d < 126

134 - 3(3) < 126

134 - 9 = 125

125 < 126

3 days
