Answer: The answer is B.
Step-by-step explanation: Multiply $15 times 5 shirts, which equals $75. Now multiply $20 times 4 shoes, which equals $80. Now add the two products, and you get $155.
OK so if 70% of students in 8th grade have siblings and 112 8th graders have siblings, then:
0.7(total 8th graders) = 112
total 8th graders = 112/0.7
total 8th graders = 160
And since the number of 8th graders is 5/6 the size of the 7th grade class:
5/6(7th grade class) = 160
5(7th grade class) = 960
7th grade class = 192.
The correct answer is D) 192.
Hope this helps

Y = 9
7y - 10y = -3y
bring down the 9 = -18 so
-3y + 9 = -18
9 - 9 = 0
- 18 - 9 = - 27
- 3y ÷ - 3 = y
- 27 ÷ -3 = 9
therefore y =9
