Question: Rohan owns a 20-square meter coconut farm. Each square meter has 2 coconut trees and each tree has 6 coconuts. If the coconuts can be harvested every 3 months and each coconut costs $0.50, how much will he earn after 6 months?
Answer with step-by-step thinking: Rohan has a total of 20 x 2 = 40 coconut trees. And he has a total of 40 x 6 = 240 coconuts. So, the total coconut he will have after 6 months is 240 x 2 = 480. Therefore, the total amount he will earn is 480 x $0.50 = $240.
So the answer is 240.


Question: Jonathan ran 7.5 kilometers. Mercedes ran twice that distance and Davonte ran 2 kilometers farther than Mercedes. How many kilometers did Mercedes and Davonte run in total?
Answer with step-by-step thinking: Mercedes = 2 * 7.5 = 15 km. Davonte = 15 + 2 = 17 km. 15 + 17 = 32 km. Mercedes and Davonte ran 32 km in total.

Question: There are some lions in Londolozi at first. Lion cubs are born at the rate of 5 per month and lions die at the rate of 1 per month. If there are 148 lions in Londolozi after 1 year, how many lions were there in Londolozi at first?
Answer with step-by-step thinking:
There are 5 - 1 = 4 more lions each month. There will be 4 * 12 = 48 more lions after 1 year. There were 148 - 48 = 100 lions in Londolozi at first.
So the answer is 100.
