Answer:
The amount of nuts is 16 kg and cereal mixture is 44 kg to obtain 60 kg of a mix that will sell for $1.40 per kg
Step-by-step explanation:
Let
x=nuts at $2.50 per kg
y=cereal at $1 per kg
x+y=60 kg (1)
2.50x+y=1.40(60) (2)
From (1)
x=60-y
Substitute x=60-y into (2)
2.50x+y=1.40(60)
2.50(60-y)+y=84
150-2.5y+y=84
-1.5y=84-150
-1.5y=-66
Divide both sides by -1.5
y=44 kg
Substitute y=44 into (1)
x+y=60
x+44=60
x=60-44
=16
x=16 kg
Answer:
p = 4.375
Step-by-step explanation:
Here we will just Cross-Multiply;
8(p) = 5(7)
8p = 35
Divide both sides by 8;
p = 4.375
( 1000 )^1/3
= ( 10 ^3 )^ 1/3
= ( 10 ) ^ 3 × 1/3
= 10
