Answer the following question.
Luna's monthly food budget is equal to 60% of her house rental budget while her phone bill budget is 10% of her food budget. If the total budget of house rental and food budget is $240, how much is Luna's total monthly budget to pay all those expenses?
Step-by-step reasoning process: Let x be Luna's house rental budget. The total budget for house and food rental is represented by the equation x + (60x / 100) = 240. The equation becomes 100x + 60x = 24000 after multiplying each term by 100 to get rid of the fraction. By combining like terms, the equation becomes 160x = 24000. Thus, the value of x is 24000 / 160 = 150 which represents the house rental budget. So, Luna's food budget is $240 - $150 = $90. Her phone bill budget is $90 x 10 / 100 = $9. Therefore, Luna's monthly budget for all those expenses is $240 (house and food) + $9 (phone) = $249.
The answer is 249.

Answer the following question.
Dawn, Lydia, and Donna have a total of 200 bananas. Dawn has 40 more bananas than Lydia. If Lydia has 60 bananas, how many bananas does Donna have?
Step-by-step reasoning process: If Lydia has 60 bananas, and Dawn has 40 more, then Dawn has 60 + 40 = 100 bananas. The total number of bananas Dawn and Lydia have is 100 + 60 = 160 bananas. Donna has 200 - 160 = 40 bananas.
The answer is 40.

Answer the following question.
CJ, KJ, and AJ collect stamps. CJ has 5 more than twice the number of stamps that KJ has, and KJ has half as many as AJ. If the three boys have 930 stamps all together, how many stamps does AJ have?
Step-by-step reasoning process: Let x represent the number of stamps for AJ. KJ:x / 2 stamps. CJ:5 + 2(x / 2) = 5 + x. Total:x + (x / 2) + 5 + x = 930. (5 / 2)x + 5 = 930. (5 / 2)x = 925. x = 925(2 / 5) = 370 stamps.
The answer is 370.
