Answer:
You subtract because you're taking away money when you're withdrawing.
You must earn 243 points to have earned 93% of all possible points.
We first multiply each percentage on the previous tests by 150:
0.88*150 = 132
0.94*150 = 141
0.9*150 = 135
The total number of points possible is given by adding up the possible points for the three previous tests and the 250 for the last test:
150+150+150+250 = 700
93% of the 700 points would be 0.93(700) = 651 points.
Now we have 132+141+135+x (last test) = 651
408 + x = 651
Subtract 408 from both sides:
408+x-408 = 651-408
x = 243
Your answer is B. -125 4/27
Answer:
Step-by-step explanation:
![\frac{3}{5}[50] = \frac{150}{5} = 30](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D%5B50%5D%20%3D%20%5Cfrac%7B150%7D%7B5%7D%20%3D%2030)
The fraction ⅗ is equivalent to 60%, so just take three-fifths of 50 to get 30.
