Using the equation, you get 12b+38=150
12b=112
B is 28/3. Your answer is correct. You round up because if you round down, then you won't have enough.
Answer: C
Explanation: Let's find each equation without any inequalities first. We have a dotted line at y = 1, so we can already remove A and B. Now, a dotted line represents exclusivity and hence; it should not include the = sign.
Thus, by elimination, the answer must be C.
When solving a word problem, it is always important to make sure you actually understand what's going on. It helps to spend some time making sure you assign the proper variables to each part of the problem before attempting to solve it.
B
Look at the pattern, they all go up by 0.5
For example, 0.5+0.5=1.0, and so fourth
Have a great day!
The equation 38 = 9k will be true when k equals 38/9. (Do 38 divided by 9 to get k, k equals 38/9, which can't be simplified any more.)
