Answer:

$19.02

Step-by-step explanation:

Paying a total of $13.15 for berries after a $3 coupon means that the coupon amount was already deducted, and she still owed $13.15.

She paid $13.15 and $7.83.

The total she paid was

$13.15 + $7.83 = $20.98

She paid with 2 $20 bills.

She paid 2 * $20 = $40

The change is $40 - $20.98 = $19.02

Answer: $19.02

2x - 3y = -5<br> 5x - 22 = -4y<br><br> Solve In Multiplication Method
Nimfa-mama [501]

Answer:

(2, 3 )

Step-by-step explanation:

Given the 2 equations

2x - 3y = - 5 → (1)

5x + 4y = 22 → (2) [ rearranged equation ]

Multiplying (1) by 4 and (2) by 3 and adding will eliminate the term in y

8x - 12y = - 20 → (3)

15x + 12y = 66 → (4)

Add (3) and (4) term by term to eliminate y, that is

23x = 46 ( divide both sides by 23 )

x = 2

Substitute x = 2 in either of the 2 equations and evaluate for y

Substituting into (2)

5)2) + 4y = 22

10 + 4y = 22 ( subtract 10 from both sides )

4y = 12 ( divide both sides by 4 )

y = 3

Solution is (2, 3 )
