Answer:
(a) we get that the fewest number of packages of cups and napkins should buy is 24.
(b) Number of sets of 3 packages of Cups and 2 packages of Napkins will be there.
Step-by-step explanation:
Given that,
Cups are sold in packages of 8.
Napkins are sold in package of 12.
To find:- (a) What is the fewest number of packages of cups and the fewest number of packages of napkins that can be purchased so there will be the same number of cups as napkins?
From the Question,
We have to least number of packages of cups and napkins So, we find the
L.C.M of the given data because it provide the least common multiple.
So, L.c.m of 8 & 12 is
Here we get that the fewest number of packages of cups and napkins should buy is 24.
(b) How many sets of cups and napkins will there be?
Again,
Number of packages of cups should buy =
Number of packages of Napkins should buy =
Hence
Number of sets of 3 packages of Cups and 2 packages of Napkins will be there.
Answer:
$318,972.30
Step-by-step explanation:
The total of 360 payments will be $318,972.30.
___
A financial calculator or app is useful for answering questions like this. Most spreadsheets have functions that will serve the same purpose.
_____
You may be given a formula for computing the monthly payment (A) from the principal (P), the annual interest rate (r) and the number of years (t). It might look like this:
A = P·(r/12)/(1 -(1 +r/12)^(-12·t))
Filling in the given numbers, you get ...
A = 154,850·(0.0557/12)/(1 -(1 +0.0557/12)^-360) ≈ 886.034154
Then the value of 360 such payments is ...
P+I = 360·886.034154 ≈ 318,972.30
___
In practice, the final payment will be different from the rest, to make up for the fact that the value of each payment was rounded down to the nearest cent. Rather than try to figure the amount of that payment, we have used a more precise value for the monthly payment and have assumed that doing so will give approximately the same total as the sequence of actual payments. (Our number here is about $2.34 low.)
