Answer:
Step-by-step explanation:
Translate the verbal statements into a system of linear equations: Fatima invested a total of $1000 in two simple-interest bank accounts. One account paid 5% annual interest; the other paid 6% annual interest. The total amount of interest she earned after 1 year was $56
Simple interest formula =
I = PRT
We are to find the Amount = Principal invested
For Account 1
I1 = P × 5% × 1
= 0.05P
Account 2
I2 = P × 6% × 1
= 0.06P
Therefore:
0.05P + 0.06P = $56

Answer:
$ 17.63
Step-by-step explanation:
Given,
The sales of the salesperson are,
$15.50, $18.98, $16.8, $14, $18.50, and $22,
Sum of sales = 15.50 + 18.98 + 16.8 + 14 + 18.50 + 22 = 105.78
Also, the number of sales = 6,
Thus, the average sale = 

= $ 17.63
