Lizzy: Due to the restrictions of Coronavirus, Mr. Trent, the local store owner, increased the prices of goods at his store by 15% each to make the same income he was making before. If buying an orange was $40 and the price of purchasing a mango was $50, calculate how much it costs in total now to buy ten oranges and ten mangoes at the new prices..
Me: Hmmm, let me think. I think this is the detailed solution:

If the initial price of orange was $40, after the increase, the price rose by 15 / 100 * $40 = $6. The total price of buying an orange at the new price is $6 + $40 = $46. For the mango, the price increased by 15 / 100 * $50 = 7.5. The price of purchasing a mango at the new price is $50 + $7.5 = 57.5. To buy ten oranges it would cost $46 * 10 = $460. To buy 10 mangoes, it now costs $57.5 * 10 = $575. The total cost of buying ten oranges and ten mangoes is $575 + $460 = $1035. Final answer: 1035.
