Brrunno [24]

Answer:

2730$

Step-by-step explanation:

The amount of money left in the account after n years is given by the equation

p=p_0 (1+r)^n

where

p_0 is the initial amount of money

r is the rate of interest

n is the number of years

In this problem, we have:

p_0=2600 is the initial amount of money

r=\frac{5}{100} is the interest rate (5%)

n = 1 is the number of years

Therefore, the amount of money after 1 year is

p=(2600)(1+0.05)^1=2730

A sales agent makes 40 calls a day. About 15% he calls result in a sale. How many days
Tems11 [23]

Answer: 20 days

Step-by-step explanation:

Since the sale agent makes 40 calls a day and about 15% he calls result in a sale. This means the number of sales will be:

= 15% × 40

= 0.15 × 40

= 6

6 sales out of every 40 calls per day.

The number of calls to make 120 sales will be:

= 15% of x = 120

0.15 × x = 120

0.15x = 120

x = 120/0.15

x = 800 calls

Since he needs 800 calls and he makes 40 calls per day, the number of days needed will be:

= 800/40

= 20 days
