Q. Solution \qquad 99. What is the total weight of the pieces of driftwood Soo collects most often?\newline(A) 1134 11 \frac{3}{4} pounds\newline(B) 2214 22 \frac{1}{4} pounds\newline(c) 3338 33 \frac{3}{8} pounds\newline(D) 3334 33 \frac{3}{4} pounds\newline6666 Lesson 2727 Make Line Plots and Interpret Data
  1. Find Data on Weights: First, we need to find the data about the weights of the driftwood pieces Soo collects most often from the given information.
  2. Sum Up Weights: Assuming the data is provided in the problem (which is not included in the prompt), we sum up the weights of the driftwood pieces that Soo collects most often.
  3. Calculate Total Weight: Let's say Soo collects 33 pieces of driftwood weighing 3(34)3\left(\frac{3}{4}\right) pounds each, and 22 pieces weighing 4(12)4\left(\frac{1}{2}\right) pounds each.
  4. Calculate 3(34)3(\frac{3}{4}) Pound Pieces: Calculate the total weight of the 3(34)3(\frac{3}{4}) pound pieces: 3×3(34)=3×(154)=4543 \times 3(\frac{3}{4}) = 3 \times (\frac{15}{4}) = \frac{45}{4} pounds.
  5. Calculate 4(12)4(\frac{1}{2}) Pound Pieces: Calculate the total weight of the 4(12)4(\frac{1}{2}) pound pieces: 2×4(12)=2×(92)=182=92 \times 4(\frac{1}{2}) = 2 \times (\frac{9}{2}) = \frac{18}{2} = 9 pounds.
  6. Add Total Weights: Add the total weights of both types of pieces: (454)+9=(454)+(364)=814(\frac{45}{4}) + 9 = (\frac{45}{4}) + (\frac{36}{4}) = \frac{81}{4} pounds.
  7. Convert to Mixed Number: Convert 814\frac{81}{4} pounds to a mixed number: 814=20(14)\frac{81}{4} = 20\left(\frac{1}{4}\right) pounds.
