Answer:
Step-by-step explanation:
Let p and s represent the costs of plain and shiny rolls of paper, respectively. The given sales let us write two equations in these two unknowns.
12p +1s = 59 . . . . . DeShawn's sale
6p +8s = 112 . . . . . Tatsakan's sale
Multiplying the second equation by 2 and subtracting the first, we have ...
2(6p +8s) -(12p +s) = 2(112) -(59)
15s = 165 . . . . . . . . . . . . . . . . . . . . . simplify
s = 11 . . . . . . . divide by 15
Substitute into the second equation to find p.
6p +8(11) = 112
6p = 24 . . . . . . . . subtract 88
p = 4 . . . . . . . . . . .divide by 6
A plain roll costs $4; a shiny roll costs $11.
