Answer:
Account A = $ 96.80
Account B = $ 48.40
Step-by-step explanation:
Account A
Principal = $1,000
rate = 2.42% = 0.0242
time = 4 years
To find the interest we will use the formula :
I = PTR
I = 1000 x 4 x 0.0242
I = $96.80
Account B
P = 1,000
t = 24 months = 2 years
r = 2.42% = 0.0242
I = PTR
I = 1000 x 2 x 0.0242
I = $ 48. 40
difference in interest = Interest a - Interest b
difference = 96.80 - 48.40
difference = $ 48 . 40
The interest on Account A doubles the interest on Account B
Answer:
solution:
x = pounds of cashews = 20
y = pounds of peanuts = 70
Step-by-step explanation:
x = pounds of cashews
y = pounds of peanuts
---
4.75x + 2.50y = 3.00*90
x + y = 90
---
put the system of linear equations into standard form
---
4.75x + 2.50y = 270
x + y = 90

f
Step-by-step explanation:
4)
pine tree is most numerous on tree farm which is 40%
5)
if 480 trees total,
pine trees = 480 x 0.40 = 192 trees
6)
if 480 trees total,
spruce trees = 480 x 0.30 = 144 trees
(p.s. also firm trees = 144 (same as spruce trees)
