1 pound is 16 ounces so multiply by .30 to get 4.80 times 2 bc theres 2 pounds which will be $9.60
Answer:.......
Step-by-step explanation:
1ml of 80ml bottle: 55/80 = 0.6875 pence
1ml of 50ml bottle: 45/50 = 0.9 pence
If no special offer the first bottle is a better value for money.
Since special offer though, you'd be buying;
50ml bottle £45 + another 50ml £22.5 = £67.5 in
which case 1ml would cost;
67.5/100 = 0.675 pence. Hence buying 2x50ml
bottle would be a better value.

x² - x - 12 ≠ 0
x² - 4x + 3x - 12 ≠ 0
x (x - 4) + 3 (x - 4) ≠ 0
(x + 3)(x - 4) ≠ 0
x ≠ -3 or x ≠ 4
(B)
Since she has $6 off for all the pizzas, she can get 10 pizzas with a $6 discount.
She would save $6 since, she has the discount and she would still have something left so she could buy something more if she wished to.
