Answer:
$108
Step-by-step explanation:
1 box = $12
18 boxes = 12×18 = $216
Total = 18×65 = 1170 pens
Cost price, Cp = $216
3 = $1
378 = 378/3 = $126
1170-378= 792 pens remaining
4 = $1
792 = 792/4 = $198
Total selling price, sp = 126+198 = $324
Profit = Sp - Cp = 324 - 216 = $108
Answer:
23+19+27+x = 96
x > 27
not sure if the answer can be left that way or do you assume that test results are whole numbers, if so then the answer would b=have to be 28.. but I think that >27 is the answer expected
Step-by-step explanation:
Answer:
x=3
y=-1
Step-by-step explanation:
first multiply the 2nd row by 2 so you will get
4x-4y=16
4x+2y=10
then subtract the 2nd row from the first row and so you will get
-6y=6
then solve for y in the above equation
y=-1
then substitute y=-1 into any 2 equations .
i picked the first 1
4x-4 × -1=16
then solve for x .
you will get
x=3
