Answer:

Step-by-step explanation:

The amount of bills are 1000

Let the number of $20 bills be x

Let the number of $50 bills be y

Using a ratio method, we assume that the ration of the bills are 20:50

Adding both ratios, we have 20 + 50 = 70.

To find x, we have

(20 ÷ 70) × 1000

0.286 x 1000

286 bills

To find y, we have

(50 ÷ 70) × 1000

0.714 x 1000

714 bills

Having calculated the number of bills for $20 and $50, we calculate the value of each bills.

we have, 286 x $20 = $5,720

714 x $50 = $35,700

Adding these above amounts, we have

$5,720 + $35,700 = $41, 420 which is approximately $41,000.

Cheers.
