The formula for simple interest is:
A = P(1+rt)
Where P = amount borrowed
r = interest rate
t = time of loan
A = 5000(1 + 0.125*2)
A =6,250
The total amount she paid back was $6,250
For her monthly payment divide total paid back by 24 months ( 2 years = 24 months)
6250 / 24 = 260.42
Her monthly payment was $260.42
Answer:
DB = 8
Step-by-step explanation:
Δ ADB and Δ BDC are similar so ratios of corresponding sides are equal, that is
=
, substitute values
= 
=
( cross- multiply )
DB² = 64 ( take the square root of both sides )
DB =
= 8
Rewrite the decimal number as a fraction with 1 in the denominator
0.225=0.22510.225=0.2251
Multiplying by 1 to eliminate 3 decimal places, we multiply top and bottom by 103 = 1000
0.2251×10001000=2251000
Answer: 30 miles per hour
Step-by-step explanation:
Speed = distance / time
= 300 / 10
= 30 miles per hour
This is a system of equations problem, so we need two equations to represent each case:
5s+5L=155
10s+12L=346
Now we isolate one of the variables.
5s = 155 - 5L
s = 31 - L
Now we substitute s in the other equation with this equation.
10(31-L) + 12L = 346
310-10L + 12L = 346
2L = 36
L = $18
Now to find s we need to plug L into one of the equations.
10s + 12(18) = 346
10s + 216 = 346
10s = 130
s = $13
A large box costs$18 and a small box costs $13
Hope this helps.
