The CPI increased from 29.6 to 82.4.
The rate of increase, is:
82.4/29.6 = 2.78
Now multiply this rate to the $0.14 price of grapes from 1960.
$0.14 x 2.78 = $0.39
Now to get the amount of increase subtract the new price from the original price:
$0.39 - $0.14 = $0.25 increase.

Answer:
Children 188
Adults. 115
Step-by-step explanation:
Let the no. of children be x and adults be y
x + y = 303
x = 303 - y. .... .....(1)
1.75x + 4.80y = 881. ...........(2)
Substituting,
1.75(303-y) +4.80y = 881
530.25 -1.75y + 4.80y = 881
530.25 + 3.05y = 881
3.05y = 881 - 530.25
y = 350.75 / 3.05 = 115 = adults
Children = 303-115 = 188
