A item in a shop is increased in price by 20% and then decreased in price by 20% a month later.
oee [108]

Answer:

Decrease of 4% ($4).

Step-by-step explanation:

Suppose the initial price was $100. An increase of 20% will make the price $120.

Now we decrease it 20% which brings it to 120 - 0.20 * 120

= 120 - 24

= $96.

So that's an overall decrease of $4 or 4%.

List the first three terms of this sequence: an = 3 • 5n – 1
Nataly [62]

Answer:

1st term = 14

2nd term = 29

3rd term = 44

Step-by-step explanation:

1st term = 3 x (5 x 1) - 1

             = 3 x 5 - 1

             = 15 - 1 =  14

2nd term = 3 x (5 x 2) - 1

               = 3 x 10 - 1

               =30 - 1 = 29

3rd term = 3 x (5 x 3) -1

               = 3 x 15 - 1

               = 45 - 1 = 44
