The 10 tons should have 37.9% cement.
Let the 25% mixture be x tons
Then the 68% mixture will be (10 -x) tons.
Using formula for mixtures:
Let p for percentage and w for weight in tons.
p₁w₁ + p₂w₂ = pw
25*x + 68*(10-x) = 37.9*10
25x + 680 - 68x = 379
680 - 43x = 379
680 - 379 = 43x
301 = 43x
43x = 301
x = 301/43
x = 7
Recall that x, was for the 25% mixture, 7 tons.
a) For the 68% mixture, = 10 - x = 10 -7 = 3 tons.
b) For the 25% mixture = x = 7 tons.
Hi Andrewkayman01pelzjin,
To find the answer to this question we need to add and subtract. So, $83 + $1200= $1283. So now, we need to subtract $896 and $272 from $1283 to get $1283 - $896 = $387 then, $387 - $272 = $115. Now, add $115 ($115 + $115 = $230) to get $230.
Your Answer Is: $230
Hope This Helps!
