Multiple Choice

Solve the problem using matrices.
-A chemist has prepared two acid solutions, one of which is 4% acid by volume, another 11% acid.

How many cubic centimeters of each should the chemist mix together to obtain 5 $$50 \mathrm {~cm} ^ { 3 }$$ of a solution
That is 6.66% acid.

A) $31 \mathrm {~cm} ^ { 3 }$ of $4 \% ; 19 \mathrm {~cm} ^ { 3 }$ of $11 \%$
B) $3.33 \mathrm {~cm} ^ { 3 }$ of $4 \% ; 46.67 \mathrm {~cm} ^ { 3 }$ of $11 \%$
C) $20 \mathrm {~cm} ^ { 3 }$ of $4 \% ; 20 \mathrm {~cm} ^ { 3 }$ of $11 \%$
D) No solution
