Marcia has two credit cards and would like to consolidate the two balances into one balance on the card with the lower interest
lakkis [162]

Answer:

Option B ,$133.92  is correct

Step-by-step explanation:

By consolidating both balances in Card B,APR of 12% would apply to funds in card A as well

Let us approach the question by solving for monthly payment of  Card A using   12% APR as follows while making use of excel pmt formula:

=pmt(rate,nper,-pv,fv)

rate is the monthly rate on the card which is 12%/12=1%

nper is the number of months of payment which is 12 months * 4 years=48

pv is the current balance in the card which is $1,389.47

fv is the total amount of monthly repayment which is taken as zero

=pmt(1%,48,-1389.47,0)=$ 36.59  

Using 16% monthly payment is $39.38  which is given already

Total monthly payments for 16%=$39.38*48=$1890.24

Total monthly payments for 12% APR=$36.59*48=$1756.32

savings in total repayments=savings in interest=$1890.24 -$1756.32 =$133.92

Which expression can be used to find 20 percent of 92? One-fifth times 92 StartFraction 1 Over 20 EndFraction times 92 One-half
Andrei [34K]

Answer:

The answer to your question is (\frac{1}{5}) 9

Step-by-step explanation:

To solve this problem we must use proportions

                     92 ---------------------- 100

                      x   ----------------------  20

Use cross multiplication to solve this proportion

                      x = 92 (\frac{20}{100})

Simplify \frac{20}{100}

              = \frac{10}{50} = \frac{5}{25} = \frac{1}{5}

Substitute this value

                                    9(\frac{1}{5}

sweet [91]

Answer:

£170000

Step-by-step explanation:

In 2010, Rafik bought a house. Let us assume Rafik bought the house for $x.  In 2015, Rafik sold the house to Bianca and made 20% profit. 20% profit = 20% of x = 0.2 × x = 0.2x. Therefore Rafik sold the house to Bianca at x + 0.2x = 1.2x. Bianca bought the house at 1.2x

The house was sold by Bianca at 5% loss in 2019. 5% loss = 0.05(1.2x) = 0.06x

Therefore the house was sold by Bianca at 1.2x - 0.06x = 1.14x. Since Bianca sold the house at £193800.

⇒ 1.14x = 193800

x = 193800/1.14

x = £170000

Rafik paid £170000 for the house in 2010
