The admission fee at a fair is $2.00 for children and $4.00
for adults.
On Saturday 2,500 people entered the fair and $7,000.00 were
collected.
How many children and how many adults attended? Give your
answer, using x for children, y for adults.
Form of: x =, and y =
Let K = no. of children
Let A = no. of adults
2500 people mean
Kids + Adults
K + A = 2500
K = 2500 – A
2K + 4A = 7000
K + 2A = 3500
(2500 – A) + 2A = 3500
A = 3500 – 2500
(A = 1000, adults)
K = 2500 – A
K = 2500 -1000
(K = 1500, Kids)
CHECK:
1500*2 = $3000
1000*4 = $4000

The estimated sum of the numbers fifty-eight (58) and twenty-nine (29) is equal to ninety (90).
<h3>What is the difference between a regular sum and an estimated sum?</h3>

- 58 = 60 as this number is nearest to 60 than to 58.
- 29= 30 because of the same reason explained above.
2. Add the rounded numbers:
