Question

zoe has a goal to sell 100 t - shirts. use the double number line to find 150% of zoes goal. the double number line has one line labeled with percentages (0%, 50%, 100%, 150%) and the other line labeled with number of t - shirts (0, 50, 100, and a blank box at the 150% mark).

Explanation:

Step1: Analyze the double number line

The right number line represents the number of T - shirts, with 0, 50, 100 marked. The left number line represents the percentage of the goal, with 0%, 50%, 100%, 150% marked. We know that 100% of the goal is 100 T - shirts.

Step2: Find the value for 150%

First, find out what 50% of the goal is. Since 100% of the goal is 100 T - shirts, 50% of 100 is $0.5\times100 = 50$ T - shirts. Then, 150% of the goal is 100%+50% of the goal. So we add the number of T - shirts for 100% (100) and 50% (50). So $100 + 50=150$.

Answer:

150
