Answer:

160 and 161

Step-by-step explanation:

x is the first page and x + 1 is the second page

combine them and you get 2x + 1

2x +1 = 321

this simplifies to

2x = 320

divide by 2

320 = 160

Rock musician Donny West is paid 15% on his CD sales and tour video sales. Last year, he sold one million CDs and 550,000 videos
Likurg_2 [28]

Answer:

Total amount of CD sales was $750,000.

Step-by-step explanation:

one million CDs were sold at $5/CD.

1,000,000 × $5 = $5,000,000

Donny gets 15% of the sales, so he'll receive the amount of CD sales as:

$5,000,000 × 15/100 = $50,000 × 15 = $750,000.

Optional:

If you add both of the multiplied values, 1,000,000 × 5 + 550,000 × 6

= $5,000,000 + $3,300,000

= $8,300,000

so, 15% of it would be $1,245,000.

if you calculate both separately and then add them, you'll still get $1,245,000.

I hope this'll help.
