Question: Gondor is a technician, he earns $10 from repairing a phone and $20 from repairing a laptop. If he was able to repair 3 phones last Monday, 5 phones last Tuesday, 2 laptops on Wednesday, and 4 laptops last Thursday, how much does he earn in total?
Answer: Gondor was able to repair a total of 3 + 5 = 8 phones from Monday to Tuesday. And the total amount he earned is $10x8 = $80. He was able to repair a total of 2 + 4 = 6 laptops from Wednesday to Thursday. So, the total amount he earned is $20x6 = $120. Therefore, the total amount he earned is $120 + $80 = $200. The answer is 200.
