Answer:
Since, company A charge of $423.5 is less than company B charge of $450
Hence,
Company A should be hired to get the better deal.
Step-by-step explanation:
Dimension of room: 11 * 14 foot
Area of rectangle is given by length * width
Thus,
area of room using above formula = 11*14 square foot = 154 square foot
For company A
charge for 1 square foot = $2.75
Charge for room = charge for 1 square foot * area of room
= 2.75 * 154 = 423.5
Thus, Total money charged by company A as calculated above is $423.5
Given,
company B charges $450 per room
Since, company A charge of $423.5 is less than company B charge of $450
Hence,
Company A should be hired to get the better deal.
Answer:
New balance = 3640
Step-by-step explanation:
Given the following data;
Interest rate = 4% = 4/100 = 0.04
Principal = 3500
To find the new balance;
First of all, we would find the amount at the interest rate;
New amount = interest rate * principal
New amount = 0.04 * 3500
New amount = 140
Now, to find the new balance;
New balance = principal + new amount
New balance = 3500 + 140
New balance = 3640
