Answer:
The formula is F = P(1 + interest percent)^n
Here,
p =8000 dollar
interest percent =5.5% = (5.5/12)/100 =0.004583 (compounded monthly)
n =7 x 12 =84 (compounded monthly)
=> Mark's account balance after 7 years
F = 8000*(1+0.004583)^84 =11746.2503 dollar
5 infinitely many
6. none
The answer is option B. In the distributive property you need to multiply the constant that is outside of the parenthesis, with the terms that are inside :)
Answer:
x = 9
y = 9
Step-by-step explanation:
Given :
Let :
Kenyan French roast coffee = x
Cost per x = $8
Sumatran Coffee = y
Cost per y = $10
x + y = 18 - - - - (1)
8x + 10y = 9 * 18 ;
8x + 10y = 162 - - - - (2)
From (1):
x = 18 - y
Put x = 18 - y in (2)
8(18 - y) + 10y = 162
144 - 8y + 10y = 162
2y = 162 - 144
2y = 18
y = 9
x = 18 - y
x = 18 - 9
x = 9
