Michael earns $900 per month, plus 5% commission on all his sales over $750. what is the minimum amount of sales Michael must ha

Alina [70]

<h3>The minimum amount of sales Michael must have to earn at least $2500 in a month is $ 32000</h3>

Solution:

The expression to Michael earnings is:

$b + (c \times s)$

Where,

b is the base salary, which is $ 900 in this sum

c is the commission rate

Given that commission rate is 5%

s is the sales

Michael must have to earn at least $2500 in a month

Here, at least means, "greater than or equal to" 2500

The inequality is framed as:

base salary + 5 % on sales $\geq$ 2500

$900 + \frac{5}{100} \times s \geq 2500\\\\\ 900 + 0.05s\geq 2500$

Solve the inequality

$0.05s\geq 2500-900\\\\0.05s \geq 1600\\\\Divide\ both\ sides\ by\ 0.05\\\\s\geq 32000$

Thus, minimum amount of sales Michael must have to earn at least $2500 in a month is $ 32000

Be:
Number of hours: n

The cost of renting a bike for the first hour is $7:
n=1→f(n)=f(1)=$7

He is charged $2.50 for every additional hour of renting the bike:
f(n)=f(n-1)+2.50, for n ≥ 2

f(1)=7; f(n)=f(n-1)+2.50, for n ≥ 2 (sixth option)

f(n)=f(1)+2.50(n-1)
f(n)=7+2.50(n-1)
f(n)=7+2.50n-2.50
f(n)=2.50n+4.50 (fifth option)

Answers:
Fifth option: f(n)=2.50n+4.50, and
Sixth option: f(1)=7; f(n)=f(n-1)+2.50, for n ≥ 2
