a housewife purchased a sofa set the was priced at $2200 cash price under HP terms she paid an initial dowm payment of 20% of the cash price and interest which is equivalent to 15% of the outstanding balance is change

Cash price of the car

Step-by-step explanation: Down payment + A(1 - (1+r/m)-nm

                                           r/m

= $2,200 + $200(1-(1+0.11/12)-4x12

                                 0.11/12

= $2,200 + $200(1-(1+0.0091666667)-48

                               0.0091666667

= $2,200 + $200(1-(1.009166666667)-48

                              0.0091666667

= $2,200 + `$200(38.691421)

= $9,938

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
