Step-by-step explanation:
what are the expressions?
Answer:
1. = station A
because 15 gallons = 0.75 discount at B but station A has a 1.50 discount at 15 gallons
Step-by-step explanation:
2. for satation B you have to read the graph
but for station A it is unclear on the graph
a way to work it out is that you know that 10= 1.00 so 12 = 1.2
( divide 12 by 10 )
station B = discount for 12 gallons = 0.6
but Station A = discount for 12 gallons = 1.2
the difference is
1.2 - 0.6 = 0.6 discount
1) 40+7=47
2) 47+7= 54
3) 54+7 = 61
4) 61+7 = 68
The answer is 68.

Standard form is taking a large number and putting it in a form where the number is smaller than 10. To do that (using the number above) you would take the first number which is 5 and then make every number after it part of a decimal. You then use [×10^x] (multiplied by 10 to the power of the amount of numbers after the decimal point (In this case 9)) to show others that to find the full number you multiply the decimal by 10 to the power of 9.
