Q: 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?
A: 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.

Q: Mom went shopping at the market. She left with €55. She bought 2 packs of bananas for €4 each, pears for €2, asparagus for €6 and finally a chicken for €11. How much money does Mom have left?

Let x be the price of the chair. The table costs 3 * x. The couch costs 3 * x * 5 = 15 * x. x + 3 * x + 15 * x = 380. 19 * x = 380. x = 20. The couch costs 20 * 15 = 300 dollars. The answer is 300.
