Final answer:
Rashid earned AED 4 per lawn, which is calculated by dividing his total earnings of AED 12 by the 3 lawns he mowed.
Step-by-step explanation:
The question is asking how much Rashid earned per lawn mowed, given that he earned AED 12 for mowing 3 lawns. To find out the unit price earned per lawn, we simply divide the total amount earned by the number of lawns mowed.
Step 1: Identify total earnings. Rashid earned AED 12 in total.
Step 2: Identify total lawns mowed. Rashid mowed 3 lawns.
Step 3: Calculate the unit price by dividing the total earnings by the total lawns mowed.
Unit price per lawn = Total earnings / Total lawns mowed
= AED 12 / 3
= AED 4 per lawn mowed.
Therefore, Rashid earned AED 4 for each lawn that he mowed.
