Answer

60%

Step 1: Find the decrease in cost. Decrease = Original cost - New cost $Decrease = sh 30 - sh 12$ $Decrease = sh 18$

Step 2: Calculate the percentage decrease. Percentage Decrease = (Decrease / Original cost) $\times$ 100% $Percentage Decrease = \left(\frac{sh 18}{sh 30}\right) \times 100\%$ $Percentage Decrease = \left(\frac{18}{30}\right) \times 100\%$ $Percentage Decrease = \left(\frac{3}{5}\right) \times 100\%$ $Percentage Decrease = 0.6 \times 100\%$ $Percentage Decrease = \text{60%}$ 3 done, 2 left today. You're making progress.

Step 1: Find the decrease in cost. Decrease = Original cost - New cost Decrease = sh 30 - sh 12 Decrease = sh 18 Step 2: Calculate the percentage decrease. Percentage Decrease = (Decrease / Original cost) × 100% Percentage Decrease = (sh 18sh 30) × 100\% Percentage Decrease = ((18)/(30)) × 100\% Percentage Decrease = ((3)/(5)) × 100\% Percentage Decrease = 0.6 × 100\% Percentage Decrease = 60% 3 done, 2 left today.
