Don put $3,000 in a savings account with an interest rate of 5% for three years. If the interest is compounded annually, how muc
nikklg [1K]
Compounded anually means
if you put x in at y percent then 
you calculate like this
if you put in x at y percent then  the money you earn is
x +(x times y)=z=first year
second year=z+(z times y)=s
third year=s+(s times y)=t

percent means parts out of 100 so 5%=5/100=0.05
'of' can be translated as multiply
so

3000 +(3000 times 0.05)=3150=fisrt year
3150+(3150 times 0.05)=3307.5=second year
3307.5 +(3307.5 times 0.05)=3472.88=tird year

he will have 3472.88  at end of 3 years

A quality control inspector examined 150 light bulbs and found 8 of them to be defective. At this rate how many degective light
choli [55]

Answer:

106

Step-by-step explanation:

For every 150 light bulbs, 8 are defective

The defective rate can be written as;

8/150

= 4/75

Now, to find the number of defective light bulbs in a lot of 2000, we simply multiply the defective rate by this amount

This gives;

4/75 * 2000

= 106.6

This is approximately 106 light bulbs because a light bulb is either defective or not so, we need to have a whole number.
