Devon owns a house cleaning company and has to give price quotes to potential customers. he figures out his price by assuming a $25 base charge and then adding $8 for each bathroom and $4 for each other room. if he uses p to represent the price and b for bathroom and r for other rooms, which of these represents his price quote formula?
a p = 25 + 12(br)
b p = 4r + 8b + 25
c p = 25(4r + 8b)
d p = (4)(8)(r + b) + 25

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.
