    Answer:

    Briana saved $1.80.

    Step-by-step explanation:

    When the sales promotion is 20% off.

    Cost price is $45

    Amount after discount is = 45-(0.20\times45)=36 dollars

    When the sales promotion is 10% off.

    Cost price is $42

    Amount after discount is = 42-(0.10\times42)=37.80 dollars

    Hence, Briana saved 37.80-36=1.80 dollars
