Let's translate this question into a formula:
Total cost = (unit price of the eraser) (number of erasers purchased)
Final total cost = (Total cost) * 1.08 = ?
Why? The Final Total Cost = Cost of the erasers + (Cost of the erasers)(sales tax rate)
Final total cost = 1.08 (Total Cost)
Final total cost = 1.08 ($0.50)(24) (since 1 dozen = 12, and 2 dozen = 24)
A poem wage for Gil = number of hours* wage per hour
= 1*10 = 10$
A poem wage for Holly = number of hours*wage per hour
= 2*10 = 20$
A poem wage for Ivan = number of hours * wage per hour
= 3*10 = 30$
And all 3 of them works for 12 hours per day.
Since Gil charges least for a poem, it is always betterr to take Gil for first 12 poems.
Let us find wage for 18 poems = (wage for 12 poems from Gil) + (wage for 6 poems from Holly) = 12*10 + 6*20 = 240$
Since both Gil and Holly worked for 12 hours to complete 18 poems.
Remaining 1 poem should be written by Ivan.
And that will cost 30$.
Hence It will cost 30$ more to commission 19 poems per day than 18 poems per day.
5 and 15: Their product is 75, and their sum is 20 (even).
