Answer:
answer correct order 1,3,2
Step-by-step explanation:
65% of 80 is 52
82% of 50 is 41
and 170% of 30 is 51
The answer to question 3 is 1 person orders chicken and the other 5 had steak dinner.
the way you work this out is you half 6 which is three and then do 3x14 and 3x17
3x14=42
3x17=51
42+51=93
this is too less so you have to do less of the cheaper meal (14) and more of the dearer one (17) so I went to 1x14 and 5x17
1x14=14
5x17=85
14+85=99
add these together and it makes 99
the answer to question 14 is 5 adults and 3 students
to do this you do exactly the same as how you do question 3
Because both answers equal y, we can set them equal to each other. So, -8x=-5x-9. Add five over to get -3x=-9. Divide and x=3. Then plug 3 in to solve for y. -8(3)=24. The ordered pair is (3,24).
It's probably 8 actually. Because you measure the AC and the CB and just subtract.
