kirza4 [7]

Answer:

Therefore the required equation is

Y=5+3X

Step-by-step explanation:

Given that , Joey has 5 collector stamps.

He gets 3 more stamps each week.

The number of week is X.

1st week he got 3 stamps

2nd week he got (3+3)=2.3 stamps

3rd week he got (3+3+3)=3.3 stamps

Stamp that he got=( the number of week ×3)

Therefore at end of Xth week he got =(X × 3) =3X stamps

Total number of stamps that collected after x week

=5+3X

Therefore the required equation is

Y=5+3X
