Answer:
a) $86.11
b) $467.33
Step-by-step explanation:
no. of gallons saved 'n' per year
n = (10000/33) - (10000/36)
n = 2500/99
Amount saved = 3.41×n = 3.41×2500/99
= $86.11
b) over 5 years:
86.11( 1 + (1.041) + (1.041)² + (1.041)³ + (1.041)⁴ )
= 86.11(5.427157431)
= $467.33
Step one: correspond x values and y values together
it would be: 3, 12 and 4, 16
Step two: divide
12/3 = 4 and 16/4 = 4
both numbers = 4
scale factor is 4

Step-by-step explanation:
- 4x-(x+7)=2(x+3)
- 4x-x-7=2x+6
- 3x-2x=6+7
- x=13
hope it helps.
