Emily has printer paper and lined paper for her classroom. The reams of printer paper have 50 sheets per ream and
cost $10. The reams of lined paper have 75 sheets and
cost $12. Emily will order a total 45 reams of paper and
her total cost is $490. What system of equations gives
the correct relationship between the p reams of printer
paper and I reams of lined paper?
O
A. {1 + p = 45
{10/ + 12p = 490
B. {1 - p = 45
{12/ + 10p = 490
C. {1 + p = 45
{12/ - 10p = 490
D. { 1 - p = 45
{10/ - 12p = 490
E. {1 + p = 45
{12/ + 10p = 490
