Vlad did not make a mistake.
(10x5)+(10x14)+(10x-3)
50+140-30
160
The answer is its in the ones place
Step-by-step explanation:
Each person's donation ratio is:
Donation 1 is 4/15 of 75
Donation 2 is 4/15 of 75
Donation 3 is 7/15 of 75
4/15(75) = 5 * 4 = 20
7/15(75) = 5 * 7 = 35
Each person's donation amount is:
$20
$20
$35
Check out work:
20 + 20 + 35 = 75!
Ok so go to the top left and multiple it by 0 and then you will still get 0 so -0 + 10x 4
