B - 3/4 = 7/10
add 3/4 to both sides to isolate the b
b = 7/10 + 3/4
b = 28/40 + 30/40
b = 58/40
b = 1  18/40
b = 1   9/20

B - 3/4 = 7/10
b = 3/4 + 7/10
b = 15/20 + 14/20
b = 29/20
b = 1 and 9/20

Calculate the total installment price the carrying charges in the number of months needed to save them money at the monthly rate
masha68 [24]

Answer:

  • the total installment is $936
  • the carrying charges are $186
  • the monthly rate to buy the items are  19.23 or 20 months

Step-by-step explanation:

$39 for 24 months comes to ...

$39 × 24 = $936

The "carrying charges" are the difference between the cash price and the installment price:

$936 -750 = $186

 Saving at the rate of $39 per month, it would take ...

  $750/$39 = 19.23 months   about 20 months to save up the cash price.

Often, such savings would come from a once-a-month paycheck, so it would take more than 19 such paychecks to save the required amount.

hope it will help :)
