Answer:22
Step-by-step explanation:
22
LCM= 40
factors of 5- 5, 10, 15, 20, 25, 30, 35, 40*
factors of 8- 8, 16, 24, 32, 40*
30% decrease
175 divided by 250 = 0.7
1 - 0.7 = 0.3
0.3 = 30%
14?
17-12=5
5x2=10
10+4 =14
The fractions you're given can be simplified down, so you get (12 ÷ 3) 4 hours on Monday, (21 ÷ 3) 7 hours on Tuesday, and (22 ÷ 3) 7 1/3 hours on Wednesday. You can now add these up and get your answer as 18 1/3 hours, or 18.33.
I hope this helps!
