Answer:
amount of interest = 52.5
amount at the end of the period = 1052.5
Step-by-step explanation:
use the formula for simple interest
PRT/100
P is the principle
R is the rate of interest charged
T is the Time taken
18 months = 1 years 6 months ( 1.5 years)
1000 * 3.5 * 1.5 = 5250
5250/100 = 52.5
the amount of interest = <u>52.5</u>
the amount she will have at the end of the period
= 1000 +52.5
= <u>1052.5</u>
Slope can be calculated using the formula: m= 
y1/x1 represents the first number in the bracket
y2/x2 represents the second number in the bracket
Calculation
m =
m = 
m= 6/-12
m= -0.5 or -1/2
Therefore, the answer is B.
Answer:
1 sub = $5.50; 1 sandwich = $4.00
Step-by-step explanation:
You can solve this using a matrix and solving using reduced row-echelon form.
-0.3125 is the answer, but you probably have to round
