Explanation / Answer
1. The sum of two consecutive even integers is at most 180.Find the pair of integers with the greatest sum. Ok so an integer is a whole number so 89+90 is almost 180 butthe greatest sum that is almost 180 is 90+91=181. 2. After selling 160 copies of the program to a school play,an usher had fewer than 40 copies left. How many copies of theprogram did the usher have originally?ok so 160 + 40= 200 because he has to have sold 160 and so he has40 left. 3. A house and a lot together cost more than $86,000. Thehouse costs $2000 more than six times the cost of the lot. How muchdoes the lot cost by itself?
6x+2000=86,000 6x=84,000 x=$14,000 4. Andrew's salary is $1200 a month plus a 4% commissionon all his sale. What must the amount of his sales be to earn atleast $1600 each month?
1.04x=1600 x=$1538.46 1.04 is the percent his salary will increase and 1600 isthe amount he wants to make. Hope that helped
