1) 4n - 4 + 4n = -4 + 8n
-4 = -4 + 8n
8n = 0
n = 0
2) -2 +6 = -4 -2a
4 = -4 -2a
-2a = 8
a = -4
3) -7 + x = 2x - 12
-x = -5
x = 5

Since sale is 40% so the price is 60%

61*(60%) = 36.6

the tax is 5%

so the price after tax is: 36.6 * (1 +5%) = $38.43

Answer:

£ 7.95

Step-by-step explanation:

Let the total money = £ x

Money spend on drinks and cake = 1.45 + 1.20 = £ 2.65

Money left with her = (2/3) of x

So, money spend = (1/3) of x

$\dfrac{1}{3}*x= 2.65\\\\\\x=2.65*3\\\\$

x = £ 7.95
