Answer:
22 kids
Step-by-step explanation:
R (red shirts)
Y (yellow shirts)
R= Y+12 (to make them equal, you need to add 12 to the yellow because it tells you that there are 12 more red shirts than yellow)
R+Y=32 (the amount of students in the class)
Substitute R from the first equation into the second one.
(Y+12) + Y = 32
2Y +12 =32 (subtract 12 from both sides)
2Y =20 (divide by 2 on both sides)
Y=10
Now you know the amount of kids wearing yellow shirts.
Subtract the whole class and the yellow shirts.
32-10= 22
Answer:
D is The correct Answer
Step-by-step explanation:
Answer: About 45.
Step-by-step explanation: There's always a pattern in these kinds of questions, you can see for 9th to 13th August, the number has always been between 20 to 40. And since on 13th August the graph is on a rise again, it would be around 45. 90 is just not realistic considering there's only an increase of around 5-10 tickets every day.
