Answer:
475 adults
Explanation:
Given: Admission price in a fair is $1.50 for children and $4 for adults.
Amount collected one day is $5050
2100 children paid the admission price.
As given 2100 children have paid the admission price.
∴ Amount of price paid by children =
![number\ of\ children * prices\ per\ child](https://img.qammunity.org/2020/formulas/mathematics/middle-school/uyy9st0cjrgzrtw6gxi8tqdu6siqf3ufl3.png)
∴ Amount of price paid by children =
![2100* 1.5 = \$ 3150](https://img.qammunity.org/2020/formulas/mathematics/middle-school/4y7d778v4sm0j6zxz67hcbjb201jvoabx2.png)
Now, finding the amount collected from adults.
Amount collected from adults =
![Total\ collection - amount\ collected\ from\ children](https://img.qammunity.org/2020/formulas/mathematics/middle-school/wgi5smxwixe1x2nn6usqd5h773uv1kau6c.png)
∴ Amount collected from adults=
![5050 - 3150 = \$ 1900](https://img.qammunity.org/2020/formulas/mathematics/middle-school/4iem2q4xixdsrot6tfn610dirxhl9fgxu6.png)
Next, finding the number of adults that paid admission.
∴ Number of adult =
![(Amount\ collected\ from\ adult)/(price\ per\ adult)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/go9y2hdy0mmwtbe9nqhj1w1m9yxiyoaal2.png)
Number of adult =
![(1900)/(4) = 475\ adults](https://img.qammunity.org/2020/formulas/mathematics/middle-school/vh1wr70rrm0uebyfd8jcdsm1pkan4nr93a.png)
∴ Total number of adults who paid the admission is 475.
