Answer:
Interest Rate on 2-Year Loan...$435.6
Interest Rate on 5-Year Loan...$1,452
Step-by-step explanation:
The formula for calculating simple interest is as follows.
I = P x R x T,
where I = interest
P= Principal
R= interest rate
T= time
For the loan at 4.5 percent for 2 years, the interest will be
= $4,840 x 4.5/100 x 2
= $4,840 x 0.045 x 2
= $435.6
Total cost of the loan will principal plus interest
=$435.6 + $4,840
=$5,275.6
Monthly loan cost
= $5,275.6/24
=$219.81
Total loan cost..$5,275.6
Monthly loan cost ...$219.81
For the Loan at 6 percent for 5 years, the interest will be
= $4,840 x 6/100 x 5
= $4,840 x 0.06 x 5
=$1,452
Total cost of the loan will be principal plus interest
=$ 4,840 + $1,45
=$6,292
Monthly costs will be
=$6,292/60
=$104.87
Total loan cost... $6,292
Monthly loan costs... $104.87
Answer:
$1.80
Step-by-step explanation:
Let the cost of a hot dog = x
The cost of a hot dog roll = y
Eight hot dogs and seven hot dog rolls cost $\$13.60$.
8x + 7x = $13.60..... Equation 1
Seven hot dogs and eight hot dog rolls cost $\$13.40$.
7x + 8x = $13.40...... Equation 2
Combining both Equation
8x + 7x = $13.60..... Equation 1
7x + 8x = $13.40...... Equation 2
Eliminating x
Multiply 1 by 7
Multiply 2 by 8
56x + 49y = 95.2..... Equation 3
56x + 64y = 107.2 ..... Equation 4
Subtracting 4 from 3
-15y = -12
y = -12/-15
y = 0.8
Cost of one hot dog roll = $0.8
Solving for x
8x + 7x = $13.60
8x + 7(0.8) = 13.60
8x + 5.6 = 13.60
8x = 13.60 - 5.60
8x = 8.0
x = 8.0/8
x = 1.
Cost of one hot dog = $1.0
The cost in dollars of a hot dog and a hot dog roll cost combined is
x + y
= $1 + $0.8
= $1.80
