1. The answer is $24
32x0.25= 8 32-8=24
2. The answer is $105
150x0.30=45 150-45=105
3. The answer is $52
80x0.35=28 80-28= 105
4. The answer is $59.25
14+25+40=79 79x0.25=19.75 79-19.75=59.25
First we turn the percent to a decimal by dividing it by 100.
25/100 = 0.25
" of " means multiply
0.25 x 204 = 51....so 25% of 204 is 51

Answer:
It is a singular matrix system.
Step-by-step explanation:
A column of all zeros in a matrices says that the variable associated with that column has no effect on the output.
For example If the first column of a matrix consists of zeros, this means that the coefficient of the first variable is zero in every equation in the system . This means that if there is any solution at all, then there must be an infinite number of them, since you can set that first variable to any value at all and still satisfy all of the equations.
