During a fundraising event, Sam donated $2.50 and Nora doncted
$8.20
Sam then had 4 times as much money as Nora hod left
How much did Nord have left?​

Answer 1

Sam Nora

x x

After donation -

Sam = x - 2.50

Nora = x - 8.20

ATQ :-

x - 2.5 = 4[x - 8.2]

x - 2.5 = 4x - 32.8

4x - x = 32.8 - 2.5

3x = 30.3

x = 10.1

Final Amount with Nora = x - 8.2

= 10.1 - 8.2

= $ 1.9

Answer 2

Answer:

$1.90

Step-by-step explanation:

Sam......... =........... Nora

$ 2.50 + 4x = $8.20 + x

.

4x - x = $8.20 - $2.50

.

3x = $ 5.70

.

x = $5.70 / 3

.

x = $1.90
