Solve the following percentages

1. £ 253,628.16

2. £ 350

3. 600,000 tickets

Step-by-step explanation:

1.

We will use compound growth formula for this, the formula is:

Where

F is future amount (what we want to find after 2 yrs)

P is present amount (240,000)

r is the rate of increase (2.8% = 2.8/100 = 0.028)

t is the time in years (t = 2 given)

Substituting, we get our

The house would be worth £253,628.16 after 2 years

2.

After the discount of 15%, he paid 297.50. So we can say:

What number, discounted by 15%, makes 297.50?

We can let that original price be "x" and write the equation as:

Originally, the laptop was worth £ 350

3.

480,000 is 80% of the total number of tickets.

If we let total number of tickets be t, we can say:

480,000 is 80% (80/100 = 0.8) of WHAT NUMBER (t)??

Now, we can write an algebraic equation and solve:

The total number of tickets available was 600,000 tickets

w'x is 0.

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
