Part 1
Given the question 'A set of 8 desert dishes costs $20. What was the cost of eah dish?'
Let the cost of each dish be x, then
8x = 20
x = 20 / 8 = 2.5
Therefore, the cost of each dish is $2.5
Part 2
Given the question 'Ben and Jerry together owns 24 comic books. If Ben owns 6 comic books, how many does Jerry own?'
Let the number of comic books owned by Jerry be x, then
x + 6 = 24
x = 24 - 6 = 18
Therefore, Jerry owns 18 comic books.
Part 3.
Given the question: 'Hans Klobber sells vaccum cleaners. He gets to keep one eighth of his sales as commission. How much must he sell in order to earn $1,000?'
Let the amount of sales required to earn $1,000 be x, then
1/8 (x) = $1,000
x = 8 times $1,000 = $8,000
Therefore, the amount of sale he must make to earn $1,000 is $8,000.
Part 4.
Given the question: 'On first down, a football team lost 8 yd. After 2 downs, the team had an overall gain of 20 yd. How many yards were gained on secong down?'
Let the number of yards gained on second down be x, then
-8 + x = 20
x = 20 + 8 = 28
Therefore, the number of yards gained on second down is 28 yards.
Part 5.
Given the question: 'After she wrote a check of $240, May Bounce had a balance in her checking account of -$6. What was her balance before she wrote the check?'
Let her balance before she wrote the check be x, then
x - 240 = -6
x = -6 + 240 = 234
Therefore, the balance in her checking account before she wrote the check was $234.
Part 6.
A bank of 8 floodlights together use 1,000 watts of power. How much power is used by each bulb?
Let the amount of power used by each bulb be x, then
8x = 1,000
x = 1,000 / 8 = 125
Therefore, the amount of power used by each bulb is 125 watts.
Part 7.
Given the question: 'Between noon and midnight, the temperature dropped 20°F. If the temperature was -8°F at midnight, what was the temperature at noon?'
Let the temperature at noon be x, then
x - 20 = -8
x = -8 + 20 = 12
Therefore, the temperature at noon was 12°F.
Part 8
Given the question 'If a strawberry pie is divided into 6 equal slice, each slice has 240 calories. How many calories are in the whole pie?'
Let the number of calories in the whole pie be x, then
1/6 (x) = 240
x = 240 times 6 = 1,440
Therefore, the number of calories in the whole pue is 1,440 calories.
Part 9.
Given the question: 'A chest was resting on the ocean floor 1000 ft below the surface. It was lifted to the deck of a ship 8ft above the surface. How far was the chest lifted?'
Let the distance the chest was lifted be x, then
-1,000 + x = 8
x = 8 + 1,000 = 1,008
Therefore, the distance the chest was lifted is 1,008 ft.
Part 10
Given the question: 'When all the kids who tried out for Little League were divided into teams of 20 players, there were exactly 8 teams. How many teams tried out?'
Let the number of kids that tried out be x, then
