19 thousands is 19 x 1000 = 19,000
7 tens is 7 x 10 = 70
19 thousands plus 7 tens is 19,000 + 70 which is 19,070.

Answer: y= 25+2.5x
Step-by-step explanation:
Let a = base pay , b = additional amount per newspaper.
Given: Last week, Pedro delivered 5 newspapers and earned $37.50.
i.e. 37.50=a+5b (i)
This week, he delivered 20 newspapers and earned $75.
i.e. 75=a+20b (ii)
Eliminate (i) from (ii)
37.50=15b
, i.e. additional amount per newspaper= $2.5
Put b= 2.5 in (i)
, i.e. base pay = $20
Let x= Number of newspapers Pedro delivers.
y= Earnings he receives in dollars.
y= 25+2.5x will be the required function.
