Answers
Reiny
number of P50 --- x
number of P20 ----48-x
their value:
50x + 20(48-x) = 1500
solve for x
number of P20 ----48-x
their value:
50x + 20(48-x) = 1500
solve for x
nexty wherl
20x+50(48-x)=1500
20x+2400-50x=1500
-30x=1500-2400
-30x=-900
-30 =-30
X=30
20x+2400-50x=1500
-30x=1500-2400
-30x=-900
-30 =-30
X=30
