Answer:
45 mins
Step-by-step explanation:
The question is how much time should the painter spend on painting a doll for the costs to still be equal or lower to $24.50
We can make this equation, representing the raw materials + the painting job (at $18/h):
$11 + $18x = $24.50
18x = 13.50
x = 13.5 / 18 = 0.75
So, the painter should spend at most 3/4 of an hour (or 45 mins) painting a doll to keep the cost at or below $24.50 per doll.

Answer:

Step-by-step explanation:
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
Given
=
and r =
, then
a
=
, that is
= 
=
( cross- multiply )
32a = 2048 ( divide both sides by 32 )
a = 64 ← first term
Thus the explicit formula is
= 64
