Answer: B
Step-by-step explanation:
<u>Given:</u>
36=<1.02D-31.2<=41
<u>Solve the compound inequality for D:</u>
36+31.2<=1.02D<=41+31.2
67.2<=1.02D<=72.2
65.9<=D<=70.8
Therefore, option (b) is correct answer
8 (1/4) = 2
0.5 (10) = 5
2-1+5 = 6

---------------------------------
3 hours = 26.25
---------------------------------
Find wages for 1 hour :
---------------------------------
1 hour = 26.25 ÷ 3 = 8.75
---------------------------------
Find wages for 8 hours :
---------------------------------
8 hours = 8.75 x 8 = $70
---------------------------------
Find wages for a week :
---------------------------------
$70 x 7 = $350
---------------------------------
Salvador
---------------------------------
2 hours = $15
---------------------------------
Find 1 hour :
---------------------------------
1 hour = $15 ÷ 2 = $7.50
---------------------------------
Find 8 hours :
---------------------------------
8 hours = $7.50 x 8 = $60
---------------------------------
Find 1 week :
---------------------------------
1 week = $60 x 5 = $300
---------------------------------
Define x :
---------------------------------
Let x be the number of weeks needed
---------------------------------
Construct equation :
---------------------------------
350x = 300x + 1000
---------------------------------
Solve for x :
---------------------------------
350x = 300x + 1000
---------------------------------
Take away 300x from both sides :
---------------------------------
50x = 1000
---------------------------------
Divide by 50 :
---------------------------------
x = 20
------------------------------------------------------------------
Answer: It will take 20 weeks.
