Jannie receives R150 pocket money per month. In the new year his mother decided to increase his pocket money in the ratio \( 6: 5 \). Calculate Jannie's adjusted monthly pocket money.

To adjust Jannie's pocket money according to the ratio \( 6:5 \), first, we need to determine the new amount. The original amount is R150. The ratio \( 6:5 \) indicates that for every R6 he will now receive, the previous amount was R5. To find the adjusted amount, we perform the following calculation: 1. Find the scaling factor: \[ \text{Scaling Factor} = \frac{6}{5} \] 2. Multiply the original amount by the scaling factor: \[ \text{Adjusted Pocket Money} = R150 \times \frac{6}{5} = R150 \times 1.2 = R180 \] So, Jannie's adjusted monthly pocket money is R180.
