Reasoning and answer: A small knife is twice the amount of the utensils that costs $10.00 so the knife costs 2 * 10 = $20.00. All total, each little kit will costs $14.00 for mitts, $16.00 for an apron, $10.00 for utensils and $20.00 for a knife for a total of 14 + 16 + 10 + 20 = $60.00. Each kit costs $60.00 and they are currently 25% off so that's a savings of 60 * .25 = $15.00. The kits are $60.00 and they are $15.00 off so they now cost 60 - 15 = $45.00. She needs to buy 3 kits and each kit costs $45.00 so that's 3 * 45 = $135.00.
The answer: 135

Susan needs to make 30 / 2 = 15 batches of the recipe. Therefore, she will need 15 * 4 = 60 potatoes. She will also need 1 * 15 = 15 teaspoons of salt. Thus she will have to buy 15 / 5 = 3 containers of salt. Therefore, she will spend 60 * $.1 = $6 on potatoes and 3 * $2 = $6 on salt. Thus, she will spend $6 + $6 = $12 on food.
The answer: 12
