Answer:
-15g+11.1+4k
Step-by-step explanation:
5g - 10g)+4K+(-10g+11.1)
-15g+11.1+4k
add like terms together
Let x = Initial Price
If we increase x by 5%, we are adding 0.05x
Therefore, the new price = x + 0.05x = 1.05x
If the ticket has increased by £2.30, £2.30 is 5% of the initial price, or 0.05x
0.05x = 2.30
x = 2.30/0.05
x = 46
Therefore, the price of the ticket before the increase was £46
You can also check this backwards by doing 46*0.05 = 2.30
180 * 365 = 65700 litres/year
65700 / 1000 = 65.7 m^3/year
0.9122 * 65.7 = £59.932 for water used
28.20 + 59.93 = £88.13 for water meter annually
£88.13 < £107 so yes, he should have a water meter.
2x+6=x+3 this is the answer
D is in the correct order
