Jack Sold 1005 Boxes Of Cookies Which is 45 less than 5 times the number of boxes sold by arnisha how many boxes of cookies did arnisha sell

210 boxes

Step-by-step explanation:

Let the boxes of cookies sold by Arshina be x.

From the information we get that,

5*(No. Of boxes Arshina sold) - 45 = 1005

Hence,

5x-45=1005

5x=45+1005

5x= 1050

x=1050/5

x=210

Total deposit in each month is $ 932.84

Step-by-step explanation:

Step 1:  Monthly interest rate.

Monthly Rate = (1+annual rate)112−1

we have  Annual rate = 3.5%

Monthly Rate = (1+0.035)112−1 = 0.0028709

Step 2:  monthly payment

Monthly payment can be determined by using below formula:

A=P×i×1−(1+i)−n

A = monthly payment amount

P = total pay amount

i = monthly interest rate

n = total number of payments

In this example we have

P=$150000 ,

i=0.0028709  and

n=12×18=216

Monthly payment = P×i×1−(1+i)−n

= 150000×0.00287091−(1+0.0028709)−216 = 430.6351−(1.0028709)−216

Monthly payment  =$ 932.84
