Answer: P(t) = $1000*2^t
Step-by-step explanation:
Ok, we know that in the week 1 the price is: p = $1000
After one week, the price doubles, so here we have: p = 2*$1000
After another week, the price doubles again, here the price is:
p = 2*(2*$1000) = $1000*2^2
Here we already can see the relation, for each week, we multiply the previous price by two, which will increase the exponent in the two by 1 unit.
Then, for week number t, the price will be:
P(t) = $1000*2^t

We know:
You have $750 to spend.
A limo costs $700.
They charge $0.15 per mile.
Since we want both sides to balance out, we simply put the solution (how much we have to spend) on one side of the equation, and then the rest on the other side as shown here:
$750 (balance) = $700 (how much renting the limo costs) + 0.15x (it's a decimal since it's 15 cents per mile; the x represents however many miles the limo can travel before it reaches the $750 cap (on the left side of the equation))
Basically:
$750 = $700 + $0.15x
Now, if you want to solve how many miles the limo can travel, simply subtract $700 from both sides (subtract it from the $750).
$750 - $700 = $50
The equation should now be $50 = $0.15x
Isolate x (divide $0.15 to both sides) so:
$50 ÷ $0.15 = 333
The limo can travel a maximum of 333 miles.
The answer is $300 because you have to multiply 25x12. 10x25=250 and 2x25=50. 250+50=300.
Answer:
f = -14
Step-by-step explanation:
given:
4 − (–5f) = –66
4 + 5f = -66 ( subtract 4 from both sides)
5f = -66 - 4
5f = -70 (divide both sides by 5)
f = (-70) / 5
f = -14
