Step-by-step explanation:
New price was increase from 100% to 109% at £1800.
By proportionality,
old price / 100% = 1800 / 109%
Cross multiply to get
old price = $1800 * 100% / 109% = £1651.38
The answer is D because it shows the proper equations for both the number of people and the cost.
Answer:
A. 5 + 2.75 · S ≤ 21
Step-by-step explanation:
So we know that it has to be less than or equal to $21 because that's all she has to spend. So we can automatically rule out the equations with ≥ because that means greater than.
We can also rule out the equations that have 50 at the very end because that's just how far she wants to travel.
The best answer is A. The possible roots of this polynomial function 9i and -9i. It is possible that this polynomial function is a quadratic equation. It has a degree of two which means there are two roots and it is possible that the positive and negative value of 9i are its roots.
