Answer:
97
Step-by-step explanation:
Marcus is aiming for an A- (90-94 percent). The question states that there is another test awaiting that is worth 100 points. In order to find the answer to the question, you need to:
1.) Add 400 + 100, to show how many points there are in total.
2.) Use the answer choices and add it to 353.
88 + 353 = 441
93 + 353 = 446
97 + 353 = 450
3.) Find the percentage of the sums.
441/500 = 88%
446/500 = 89%
450/500 = 90%
Since Marcus is aiming for an A-, we can conclude that obtaining 97 points will help Marcus achieve an A-.
Answer:
H. the number of orchestra seat is 900
Step-by-step explanation:
Step one:
let the number of orchestra seat be x
and balcony seat be y
cost of orchestra= $50 each
cost of balcony =$40 each
total tickets= 1500
x+y= 1500----------1
amount earned= $69000
50x+40y=69000--------2
The system of equation for the situation is
x+y= 1500----------1
50x+40y=69000--------2
from 1, x=1500-y
put this in equation 2
50(1500-y)+40y=69000
75000-50y+40y=69000
-10y=69000-75000
-10y=-6000
divide both sides by -10
y=-6000/-10
y=600
put y= 600 in equation 1
x+600= 1500
x=1500-600
x=900
