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

The quantity of fruit pies sold was
The quantity of juice bottles sold was
Part b) Mr. Kelly’s class earned more money
part c)
Step-by-step explanation:
Part a)
Let
x-----> quantity of fruit pies sold
y----> quantity of juice bottles sold
we know that
-----> equation A
----> equation B
substitute equation A in equation B
bottles of fruit juice
Find the value of x
------> fruit pies
Part b) Which class earned more money?
Mr. Sanchez’s class
Mr. Kelly’s class
therefore
Mr. Kelly’s class earned more money
Part c) How much more money did that class earn?
Find the difference
Step-by-step explanation:
-3(2x-3)=6x+9
-6x+9=6x+9
-6x-6x=9-9
-12x=0
x=0
Answer:
Step-by-step explanation:
hello :
5(x + 7)² = 245
(x + 7)² = 49
x=0 is solution but you have other solution -14 because :(-14+7)² = (-7)² =49
here is an solution Step-by-step :
(x + 7)² = 49 means : (x + 7)² = 7²
(x + 7)² - 7²=0 use identity : a²-b² = (a-b)(a+b)
a=x+7 and b= 7
(x+7-7)(x+7+7) = 0
x(x+14)=0
x=0 or x+14=0
so : x=0 or x= -14
