Your local gas station is having a price war. during the past 7 days they have lowered the price of regular gas by $.02 each day. define a variable. then write and solve an equation to find the total change in gas. show your work. need answer asap step by step

P= Price

O= Original price

N= Number of days

P= O - (N * 0.02)

EXAMPLE:

O= 50

N= 1 day

P=  50 - ( 1* 0.02) = 49.98

N= 2 days

P=  50 - ( 2* 0.02) = 49.96

N= 3 days

P=  50 - ( 3* 0.02) = 49.94

N= 4 days

P=  50 - ( 4* 0.02) = 49.92

N= 5 days

P=  50 - ( 5* 0.02) = 49.90

N= 6 days

P=  50 - ( 6* 0.02) = 49.88

N= 7 days

P=  50 - ( 7* 0.02) = 49.86

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
