Answer:

The number of

1) 20 dollar bills = 21

2) 5 dollar bills = 105

Step-by-step explanation:

Given,

Delia has 945 dollars in 20 dollar bills and 5 dollars bills. Also she has 5 times as many 20 dollar bills. We need to find the amount of bills she has.

Let x be the number of 20 dollar bills.

Let y be the number of 5 dollar bills.

20x + 5y = 945 -(1

y = 5x -(2

Substituting (2 in (1

20x + 5x * 5 = 945

20x + 25x = 945

45x = 945

x = 945 / 45

x = 21

y = 5x

y = 5 * 21

y = 105
