Step-by-step explanation:

dont be rude

Step-by-step explanation:So you know Sara had $211 total to spend on her books, so we can set our equation equal to $211. You also know she bought 6 books but you don't know what they each cost. We can assume that they cost the same amount, so we can define this as 6x because you know you bought six books for some unknown amount of money. We also know she didn't spend $13 of the dollars, so we can think that she actually only spend $198 (211-13) on books.

So our equation would look like:

$211 = 13 + 6x   We subtract 13 from each side to solve for x

-13       -13

198 = 6x             We divide each side by 6 to get x alone because any number over itself is 1

 6       6

x = $33               Solve. So Sara spend $33 for each

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
