Is my solution correct? Will my if statement compare the 3 values and come up with the best by? Please enlighten me... Problem Statement Rebecca needs to buy a bag of Milie meal. She wrote down the prices of 500 g, 750 g and 1 kg of Milie meal. Determine which one of the packets is the best buy. Do the calculations and display which packet she should buy. The user should be prompted to enter the prices for all three packets. My answer is as follows variables used: price500g real price750g real price1kg real bestBuy string if price500g * 2 < price1kg AND price750g + 250 then bestBuy = 500g else price750g + price750g / 3 < price500g * 2 and price1kg then bestBuy = 750g else price1kg < price500g * 2 AND price750g + price750g / 3 bestBuy = 1kg endif endif endif ~Display results display "The Milie meal to buy is", bestbuy end

Code: `if price500g * 2 < price1kg AND price750g + 250` Change the bold to price750g*(4/3) . This would give us the price for 1000g (equivalent). Code: `price750g + price750g / 3 < price500g * 2 and price1kg then` We found the price of 500g in the first part, so you don't need to multiply price500g*2, instead we need to divide price1kg by two. Code: `price1kg < price500g * 2 AND price750g + price750g / 3` The first part looks good but for the second part we need to multiply price750g by four and divide that by 3. For example... Code: ```price500g price750g price1kg if(price500g < (price750g*2/3) && price500g < price1kg/2) bestBuy = price500g; else if() . . . else if() . . .``` Of course the programming language would determine exactly how that looks.
