Answer:

x=6

Step-by-step explanation:

6(2x -11) 15 =21

6 × 2x = 12x

6 × -11 = -66

12x -66 + 15 = 21

-66 + 15 = -51

12x -51 = 21

-51 + 51 = 0

21 + 51 = 72

12x = 72

12x ÷ 2 = 0

72 ÷ 12 = 6

x = 6

At a car dealership, salespeople earn a 5% commission on the first $10,000 of every sale, plus a 3% commission on any amount ove
o-na [289]

Answer:

The total comission on the sale was $375.

Step-by-step explanation:

Since the salesperson sold the car for $12,300, the total comission on the sale would be equal to the 5% of $10,000 plus the 3% of the remaining amount which would be:

Total comission=(10,000*5%)+(12,500-10000)*(3%)

Total comission=500+(2,500*3%)

Total comission=300+75

Total comission=375

According to this, the answer is that the total comission on the sale was $375.

Glen collects a total of 450 stamps from the United States,Great Britain,and India. In his collection, 52% of the stamps are US
777dan777 [17]
50% of 450 = 225
2% of 450 = 4.5 x 2 = 9
so 52% of 450 is 234 (US Stamps)

450 - 234 = 216
216 / 8 = 27

27 x 5 = 135 (British Stamps)
<span>[135 / 450 = 3 / 10 = 30%]
</span>
27 x 3 = 81 (Indian Stamps)
[81/135 = 3/5]

~

Indian Stamps 81
British Stamps (% of collection) 30%
