7-11 mini-mart started a promotion where you can buy a refillable 40 oz. Soda for a one-time price $6.00, then fill the cup for
$0.79 per year for a year or you can buy their filled disposable 32 oz. Soda cup for $1.69. How many sodas do you need to buy to make it work buying the refillable cup?
What you do is multiply regularly then add the negative sign, but if your multiplying 2 negatives it’s a positive answer. I cant help with the Fractions caz I’m not good at them lol .
