Answer this question:John bakes 12 coconut macaroons, each weighing 5 ounces. He then packs an equal number of the macaroons in 4 different brown bags, ready for delivery. When he briefly leaves the kitchen to pick the phone, his little brother Steve eats the entire contents of one of the brown bags. What is the total weight, in ounces, of the remaining coconut macaroons?
Each brown bag has 12 / 4 = 3 macaroons. After Steve eats a bag, there are 12 - 3 = 9 macaroons left. The total weight is therefore 9 * 5 = 45 ounces.
The answer is 45.

Answer this question:Marla is mixing a particular shade of lilac that's 70% blue paint, 20% red paint, and the rest white paint. If she adds 140 ounces of blue paint, how many ounces of white paint does she add?
First find the total amount of paint Marla mixes by dividing the amount of blue paint by the percentage of the paint that's blue: 140 ounces / .7 = 200 ounces. Then multiply the total amount of paint by the percentage that's white to find the number of white ounces: 200 ounces * 10% = 20 ounces.
The answer is 20.

Answer this question:Jim starts with $80 in his investment portfolio. After 1 year it grows by 15%. He then adds another $28 to his portfolio. After 1 more year the combined portfolio grows by 10%. What is his final portfolio worth after 2 years from when he started?
After 1 year Jim has gained $80 * 0.15 = $12. Therefore, after 1 year his portfolio has grown to $80 + $12 = $92. He then adds $28 to this total, so his new portfolio total is $92 + $28 = $120 at the beginning of year 2. Next, this total grows by 10%, so he gains $120 * 0.10 = $12 across year 2. Thus, after year 2, his portfolio is worth $120 + $12 = $132.
The answer is 132.
