The number of adults is 42.
The number of children is 196.
<u>Step-by-step explanation</u>:
- Adult admission = $13
- Child admission = $4
- Total people = 238
- The total bill amount = $1330
Let 'x' be the number of adults.
Let 'y' be the number of children.
The equations are,
x+y = 238 --------(1)
13x + 4y = 1330 ---------(2)
Multiply eq(1) by 4 and subtract eq(2) from eq(1)
4x+4y = 952
-(<u>13x+4y = 1330</u>)
<u>-9x = -378</u>
x = 378/9
x = 42
∴ The number of adults = 42
Substitute x=42 in eq(1)
42+y = 238
y = 238-42
y = 196
∴ The number of children = 196
Answer:
