6 A man invests $4500 in a bank. The bank pays 8% interest. a Work out the interest, in dollars.
b Work out the total.

principle amount=$4500

interest=8%

now

a) interest amount= 8/100*4500

hence interest amount is $360

b) total amount (with interest)=$4500+ interest =$4500 +$360=$4860

hence the bank pays $4860 in total

y=51

Step-by-step explanation:

We know that the two outer angles of a triangle are equivalent to the outer angle if both the angle and the triangle are on a straight line.

So,

If we add like terms on the left side, we get  

Now, let’s add 4 to each side. If we do, we get

Finally, we subtract y from each side to find y. Thus,
