Answer:
A A AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
Step-by-step explanation:
<span>w - amount of wheat purchased
r - amount of rye purchased
12w+15r=18.30 /*2
15w+10r=16.75 /*3
24w+30r=36.60, subtract this equation from the other one
45w+30r=50.25
21w=13.65
w=13.65/21
w=0.65 is a cost per pound for wheat flour
From the first equation we have
r=(18.30-12w)/15
r=(18.30-12*0.65)/15
r=0.70 is a cost per pound for rye flour</span>

Answer:
A = $3294.73
Step-by-step explanation:
Use the compound amount formula:
A = P(1 + r/n)^(n*t), where n represents the number of compounding periods per year.
Here,
A = $1600(1 + 0.024/12)^(12*30)
= $1600*(1 + 0.002)^(12*30)
= $1600(1.002)^360
A = $3294.73
