20 POINTS AND BRAINLIEST This table shows the value of a computer as a function of time elapsed since the
computer was manufactured.
Time:
1
2
3
Value:
$400.00
$100.00
$25.00
The value of the computer decreased exponentially throughout the five-year
period. What was the average annual amount of decrease (in dollars per year)
over the two-year interval from t = 2 to t = 4?

17   x 256=4352

sorry if this is wrong, i'm new.

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
