Not including tax, a total of 19 pens and markers cost $11.50. the pens cost $0.25 each, and the markers cost $0.75 each. which system of equations could be used to solve for the number of pens (p) and the number of markers (m) bought?
a.) { p + m = 30.5
{ 0.25p = 0.75m
b.) { p + m = 19
{ 0.25p + 0.75m = 11.5
c.) { p + m = 11.5
{ 0.25p + 0.75m = 19
d.) { 19( p + m ) = 1.00
{ 0.25p + 0.75 = 11.5

The graph below shows the price of different numbers of mats at a store: a graph is shown. the values on the x axis are 0, 2, 4, 6, 8, 10. the values on the y axis are 0, 21, 42, 63, 84, and 105. points are shown on ordered pairs 0, 0 and 2, 21 and 4, 42 and 6, 63 and 8, 84. these points are connected by a line. the label on the x axis is number of mats. the title on the y axis is price in dollars. which equation can be used to determine p, the cost of b mats?
