In this problem, we have the following variables:
e: The weekly earnings of a salesperson
s: sales in a given week
A salesperson earns $200 a week plus a 4% commission on her sales, that is, she earns:
<em>$200 plus 0.04 of her sales in a given week</em>
In a mathematical model, this is given by:
e = 200 + 0.04s
If Joe collected 94 stamps which are in April May and June, we could make an equation like this: A + M + J = All stamps
Plug in the values:

Isolate J:

Combine like terms:

He collected 33 stamps in June.
No change because it went down and up by the same amount
1) 16x16= 256ft
16x3x4= 192ft
add them together
256+192= 448ft2 (2 is the little number at the top next to the unit)
2) 3.14x7(2)= 153.86ft2
and i’m not sure on the other part SORRY
