About 31%
You add all of the numbers up to find out how many cans there are overall. Then take 80(cans of tuna) / overall cans and get around 31%.
We have the following vectors:
u = <-6, -2>
v = <-2, 3>
Let's multiply each vector by its corresponding scale:
-3u = <18, 6>
2v = <-4, 6>
Now we add the new vectors:
-3u + 2v = <18, 6> + <- 4, 6>
-3u + 2v = <(18-4), (6 + 6)>
-3u + 2v = <14, 12>
Answer:
-3u + 2v = <14, 12>
Answer:
70% off
Step-by-step explanation:
Calculate both these deals, then figure out which costs less.
1. 70% off
- (70% = .70)
- 70% of 998.97 = .70 * 998.97 = $699.279 is the discount
- Subtract this from 998.97: 998.97 - 699.279 = <u>$299.691</u>
2. $650 off
- Subtract 650 from 998.97: 998.97 - 650 = <u>$348.97</u>
This makes sense, because 650 is 65% of the original cost, which is less than 70%!
