The table models the cost, why, of using a high efficiency washing machine and a standard washing machine over X number for years.
1. Which equation represents the cost of the high-efficiency washing machine over a given number of years.
y = 25x + 500
y = 25x + 525
y = 50x + 500
y = 50x + 525
2. Which equation represents the cost of the standard washing machine over a given number of years?
y = 25x + 430
y = 30x + 400
y = 60x + 400
y = 60x + 430
3. After how many years of use would the washing machines cost the same amount?
9 years
10 years
19 years
20 years
4. Which washing machine would be the more practical purchase if kept for 9 years?
-high efficiency machine
-standard machine
-costs would be the same

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
