(10+2x)(8+2x) = 120

x^2 + 9x + 20 = 30

x^2 + 9x - 10 = 0

(x+10)(x-1) = 0

Answer: a loss of 4 cents

<u>Step-by-step explanation:</u>

The probability of rolling a sum of 2, 3, 4, 5, or 6 is $\dfrac{15}{36}$ which earns $2.00

The probability of rolling a sum of 28, 9, 10, 11, or 12 is $\dfrac{15}{36}$ which loses $2.00

The probability of rolling a sum of 7 is $\dfrac{6}{36}$ which loses $0.25

$\bigg(\dfrac{15}{36}\times \$2.00\bigg)+\bigg(\dfrac{15}{36}\times -\$2.00\bigg)+\bigg(\dfrac{6}{36}\times -\$0.25\bigg)=\boxed{-\$0.04}$
