Saiah Copeland sells tennis equipment. He is guaranteed a minimum monthly salary of $1,500 per month plus 5.75% of his total sal

torisob [31]

Answer:

Total sales= 10000

Step-by-step explanation:

Given data

monthly salary=$1500

commission on total sales= 5.75%

gross pay=$2,075

Firstly, let us deduct the salary

2075-1500=$575

so Saiah earned a commission of $575

let the total sales be x

so 5.75% of x= $575

5.75/100*x=576

0.0575x=575

x=575/0.0575

x=10000 sales

The bracelet Lily would like to buy costs $5 less than 5 times the amount she has saved . The bracelet costs $30. How much money

pochemuha

Lily has saved $ 7

<em><u>Solution:</u></em>

Given that bracelet costs $30

The bracelet Lily would like to buy costs $5 less than 5 times the amount she has saved

Cost of bracelet = $ 30

From given statement,

Cost of bracelet = 5 times the amount she has saved - 5

Let "x" be the amount saved by lily

Cost of bracelet = 5 times x - 5

Here "times" represents multiplication

30 = 5(x) - 5

30 = 5x - 5

30 + 5 = 5x

5x = 35

On dividing 35 by 5 we get 7

x = 7

Thus Lily saved $ 7
