I would say B , even though I’m only in 5 th grade
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
Answer:
X= -7 ± √17 / 16
x= - 0.7798...
Step-by-step explanation:
1532 ÷ 36 = 42 and remain 20.
So there were 20 CDS in the remains box
