Answer:
(a) $1.32 per pen.
Step-by-step explanation:
(a) The total amount, $31.68, distributed amongst 24 pens, equates to each pen costing a total of $(31.68/24) = $1.32 per pen.
(b) The total amount of money which Mia will have to spend on pens this yeah is $(1.45*30) = $43.5, which is $11.82 more than $31.68. Therefore, Mia will need to spend $11.82 more on pens this year.

ANSWER IS 5
so
how many years ago=x
so
'in how many years ago (-x) was ethan 5 times older than son
40-x means ethan's age x years ago
12-x means son's age x years ago
so
ethan's age x years ago is 5 times as much as son's age 5 years ago
40-x=5(12-x)
distribute using a(b+c)=ab+ac
40-x=60-5x
add 5x
40+4x=60
subtract 40
4x=20
divide 4
x=5
