Answer:
the total number of profits made at the fair was $48. each person had to pay $8 to get in. how many people were at the fair
Step-by-step explanation:
The formula for this is d=rt where d= distance, r= rate of travel, and t= time
d= 3(.083) (5 minutes divided into 60 minutes per hour)
You could also convert the miles per hour to miles per minute and use the 5. 3/60= .05 miles per minute.
d= .05(5)
d= .25 miles
d= .249 miles
The system of linear equations represents the situation is;
x + y = 125
x + y = 1255x + 8y = 775
<h3>Simultaneous equation</h3>
Simultaneous equation is an equation in two unknown values are being solved for at the same time.
let
- number of quick washes = x
- number of premium washes = y
x + y = 125
5x + 8y = 775
From equation (1)
x = 125 - y
5x + 8y = 775
5(125 - y) + 8y = 775
625 - 5y + 8y = 775
- 5y + 8y = 775 - 625
3y = 150
y = 150/3
y = 50
x + y = 125
x + 50 = 125
x = 125 - 50
x = 75
Therefore, the number of quick washes and premium washes Monica’s school band had is 75 and 50 respectively.
