Question

Donald has x twenty-dollar bills and 1 10 ten-dollar bill.

Answer 1

Answer:

y=20x+10

Step-by-step explanation:

Given:

Donald has x $20 bills and 1 $10 bills.

Let y be the total amount Donald has.

To calculate his total, we multiply the value of each bill by its frequency then sum:

$y=x\times 20+1\times 10\\\\=20x+10$

Hence, the expression of Donald's total is given as y=20x+10
