Karen and Wayne need to buy a refrigerator because theirs just broke. Unfortunately,their savings account is depleted, and they will need to borrow money in order to buy a new one. Sears offers them an installment loan at 15% (add-on rate). If the refrigerator at Sears costs $1,500 plus 5% sales tax, and Karen and Wayne plan to pay for the refrigerator for 2 years, what is the monthly payment?

Answers

Answer:

$53.14

Step-by-step explanation:

Add-on-rate = 16%

Cost = $1,578 + Sales tax = 5%(5% of $1578 = $78.90)

Time = 3 years

Total amount borrowed = 1578 + 78.90 = $1656.90

Charges = 16%

So, 16% of 1656.90

= 16/100 * 1656.90

= $265.10

Total amount would be = 1656.90 + 256.10 = $1913

No. of months in 3 years = 36months

∴ Monthly payment = [tex]\frac{1913}{36}[/tex]

= $53.14.

On Monday morning Sergio Pappas had $14.78 in cash.
During the week he earned $45.00 for cutting lawns
and $35.75 for yard work, and he spent $25.23 on food
and $22.12 on gas.
# Problem Solution
a. What were Sergio's total earnings for the week?
b. What total amount did he have to spend during the week?
c. What was his balance at the end of the week?

( please do not comment if you do not know the answer, would be appreciated )

Answers

Answer:

Step-by-step explanation:

a-As he had earned $45.00 for cutting lawns and had earned $35.75 for yard work during the week and had not earned more than that, in order to find the total amount of money he earned during the week, we have to add $45.00 and $35.75 together which will be $80.75. So we can say that he had earned $80.75 during the week.

b- Since he had spent $25.23 on food and $22.12 on gas, we have to add them to get the total amount of money spend during the week. So after adding the amount of moneys spent, we will get $47.35.

c- Finally, to find out how many money he was left with, we have to subtract the amount of moneys spent from the total amount of earnings for the week. So, after subtracting $47.35 from $80.75 he is left with $33.4.

If there are 4 ships at a port and the first one leaves and comes back every three weeks, the second one every nine weeks, the third one every 12 weeks, and the fourth every 24 weeks when will they all be in the port at the same time/when will they be there all at the same week

Answers

Answer: After 72 weeks they will be in the port at the same time.

Step-by-step explanation:

Given, Total ships = 4

The first one leaves and comes back every 3 weeks, the second one every 9 weeks, the third one every 12 weeks, and the fourth every 24 weeks .

So, the number of weeks they will take to  be in  the port at the same time = L.C.M. (3, 9, 12 , 24)   (L.C.M. = least common multiple)

Since, 9= 3 x 3

12 = 2 x2 x 3

24 = 2 x 2x 2 x3

then, L.C.M. (3, 9, 12 , 24)= 2 x 2x 2 x 3 x3 =72

Hence after 72 weeks they will be in the port at the same time.
