Answer:

290

Step-by-step explanation:

This may not be right but I used the equation f(x) = 3(10)^{2} - 10.

f(x) = 3(10)^2 - 10\\\\f(x) = 3(100) - 10 \\\\f(x) = 300 - 10\\\\f(x) = 290

Gloria, Tina, and Kelly went to an office supply store. Gloria bought 5 pencils, 7 markers, and 8 erasers. Her total was $19.00.
FromTheMoon [43]

Answer:

Pencils cost $2

Markers cost $1

Erasers cost $0.25

Step-by-step explanation:

Let pencils be denoted by P, markers by M and erasers by E. The following linear system can be modeled from the data provided:

5P+7M+8E = 19\\7P+5M+8E=21\\4P+8M+7E =17.75

Solving the linear system:

2P-2M= 2\\P=1+M\\4+4M+8M+7E =17.75\\\\12M+7E = 13.75\\12M+8E=14\\E=0.25\\M=\frac{14-0.25*8}{12}\\ M=1\\P=1+1=2

Pencils cost $2

Markers cost $1

Erasers cost $0.25
