Answer:
15 quarters
Step-by-step explanation:
15 quarters = $3.75
21 dimes = $2.10
15 + 21 = 36 coins
3.75 + 2.10 = 5.85
The answer would be 100 feet.
Using a grid, I found the answer. The problem said that each unit is 5 feet, right? This would mean that each square would be 5 feet. Counting by 5's means that you'll find the answer by each square. Just count the distance and multiply by 5. You'll get it, trust me.
15% of 80 is 12.
To check this, you can multiply 80 x 0.15, which gives you an answer of 12.
Attendance with the higher ticket price is ...
... $1750/$7 = 250
So the percentage change in attendance is ...
... change = (new - original)/original × 100%
... = (250 -300)/300 × 100% = -1/6×100% ≈ -17%
