First we get 15% from the 84.50 and then get the 10% off of that.Important: DO NOT mix the percentages thinking it will work. Percentages off does not work this way. FirstLets split 15% into 2 partsTaking 10% of something makes the decimal place move over to the left.So10% x 84.50 is 8.455% means cutting it in half8.45 x 5% = 4.23 centsNow we add them both 8.45 +4.23 = 12.68Now lets subtract 84.50 by 12.6884.50-12.68 = 71.82 - this is the 15% discount.Now we need to take 10% off of 71.82. Well we know 10% means move the decimal to the left once71.82 x 10% = 7.18Now lets take 7.18 from 71.8271.82 -7.18 = 64.65 which is answer B

Basic cable television service, which includes16 channels, costs $15 a month. The initiallabor fee to install the service is $25.

As a member of FEMA, you're required to set up a contingency plan to supply meals to residents of a town devastated by a tornado. A breakfast ration weighs 12 ounces, and the lunch and dinner rations weigh 18 ounces each. Assuming a food truck can carry 3 tons and that each resident will receive 3 meals per day, how many residents can you feed from one truck during a 10-day period?(A) 150 residents(B) 200 residents(C) 250 residents(D) 300 residents

(B) 200 residentsFirst find how many ounces of rations each truck can hold. One ton = 2,000 lbs, so one truck can carry three times that, or 6,000 pounds. There are 16 ounces in a pound, so one truck can carry 96,000 ounces: 6000 lb. x 16 oz = 96 000 oz.Then figure out how many daily rations are in a truckload. The total daily ration for each resident is 12 ounces+ 18 ounces+ 18 ounces = 48 ounces. You can express the number of daily rations supplied as 96,000 oz/48 oz= 2000 daily rations. These rations need to last 10 days. Dividing 2,000 by 10 days results in 200 residents who can be fed by one truck during this 10-day period.

If a worker earns $200 for the first 40 hours of work in a week and then is paid one and one half times her regular rate for any additional hours, how many hours must she work to make $230 in a week?A. 43B. 44C. 45D. 46

B. 44First figure out his regular rate of pay. Divide the amount of $200 / 40 hours = $5 per hour. The girl is paid 1 1/2 times his regular rate during overtime, so when working more than 40 hours he makes 3/2 x $5 per hour = $7.50 per hour. It takes him 40 hours to make the first $200. The last $30 are made at the overtime rate. Since it takes the man one hour to make $7.50 at this rate, you can figure out the number of extra hours by dividing $30 by $7.50 per hour. $30 / $7.50 per hour = 4 hours. The total time needed is 40 hours plus 4 hours, or 44 hours.
