Answer:
$39
Step-by-step explanation:
First, let's get the values of each number by <u>rounding them off to the nearest dollar before adding them</u>.
- Remember that you have to <em>round off the number up</em> if it is being followed by a number<em> </em><u><em>equivalent to 5 and above.</em></u><em> </em>You have to <em>retain the number</em> if it is followed by a<u><em> number less than 5</em></u>.
1. $2.69 = $3
2. $14.45 = $14
3. $8.05 = $8
4. $13.95 = $14
Now that you have the rounded off numbers, you may add them.
Let's solve.
- $3 + $14 + $8 + $14 = $39
The estimated total is $39.
Answer:
see below
Step-by-step explanation:
The problem statement seems to presume you have seen an exponential function like this written as ...
f(t) = a0·(1 +r)^t
where a0 is the value corresponding to f(0) and "r" is the fractional rate at which the value increases for each increment of t.
Here, 1+r corresponds to 1.04 in the given function, so r = 0.04 = 4%. When the value is <em>greater than 0</em>, it means there is an <em>increase</em> by that fraction each time t increases by 1.
Here, t is not defined, either, but it would usually be used to represent years in a situation like this. (In other situations, it might represent months, hours, or millenia.)
Hence, the appropriate choice is the one that describes a 4% annual increase.
