a shopkeeper bought 16 boxes of pens.each box contained m pens.10 pens were sold on the first day.
(a) how many pens were left after the first day?give ur answer in terms of m.
(b) if m=5,how many pens were left after the first day?
a. Pt = 16boxes * m pens/box = 16m = Total # of pens bought.
a. Bal. = 16m - 10.
b. Bal. = 16*5 - 10 = 70 pens left.
Boxes of pens = 16m
Sold pens = 10
A.) 16m - 10
B.) 16(5) - 10
Boxes of pens = 16m
Sold pens = 10
A.) 16m - 10
B.) 16(5) - 10
80 - 10
= 70
To answer these questions, let's analyze the given information step by step.
(a) To find how many pens were left after the first day, we need to subtract the number of pens sold from the total number of pens bought.
The shopkeeper bought 16 boxes of pens, and each box contained m pens. So, the total number of pens bought is 16m.
If 10 pens were sold on the first day, we subtract 10 from the total number of pens bought to find the number of pens left:
Number of pens left = Total number of pens bought - Number of pens sold
= 16m - 10
= 16m - 10
Therefore, the number of pens left after the first day is 16m - 10, where m represents the number of pens in each box.
(b) However, you mentioned that m = 5.
Substituting m = 5 into the equation we derived in part (a), we can find the number of pens left after the first day when m = 5.
Number of pens left = 16m - 10
= 16 (5) - 10
= 80 - 10
= 70
Therefore, when m = 5, the number of pens left after the first day would be 70.
