Answer:
3
Step-by-step explanation:
Let a,b & c be the number of cookies Adrian, Bobby and Calvin baked respectively.
(a+b+c)/3 =138
(a+b)/2 =136
a+b=272
a=272-b
(b+c)/2 =125
b+c=250
c=250-b
Sub a=272-b and c=250-b into (a+b+c)/3 =138,
(a+b+c)/3 =138
[(272-b)+b+(250-b)]/3 = 138
272-b+b+250-b = 414
-b = -108
b=108
From the above,
a=272-b
=272-108
a=164
c=250-b
=250-108
c=142
∵ a=164
b=108
c=142
∴ Adrian baked 164 cookies.
Bobby baked 108 cookies.
Calvin baked 142 cookies.
Hello from MrBillDoesMath!
Answer:
36
Discussion:
From the problem statement
(3/4) x = 27
where "x" is the number to be found.
Multiply both side of the above equation by (4/3):
(4/3)(3/4)x = 27 (4/3) => as (4/3)(3/4) = 1
1x = 27 * 4/3 = 108/3 = 36
