Zach bought a gold necklace originally priced at $50 but on sale for 60% off. After 10% sales tax, what was the total cost? *

$22

Step-by-step explanation:

First we calculate for the sale price.

We have to find how much is 60% of 50.

We do this by:

This equals 30.

We now subtract the 30 from the 50 to get our sale price.

The sale price is $20.

Now we have to add a 10% sales tax. This is done by multiply the percentage and adding 1 to it like this.

This equals 1.1

This is what we will multiply the $20 by.

The total cost is $22.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
