7 % of cost price is 2.80 , What about 1%?
7 = 2.80
1 = x (where x is the price value of 1% in dollars)
We simplify the above equation, so:
7 × x = 2.8 × 1 → 7x = 2.8 → x = 2.8 / 7 → x = 0.4 dollars
We know that 100% represents the whole price,
so if 1% is 0.4 dollars, then 100% will be 0.4 × 100 = 40 dollars
Therefore the store charged $40 dollars for the helmet before tax

Answer:
; At-least 15 questions.
Step-by-step explanation:
Let x represent the number of questions you need to answer correctly..
We have been given that each question is worth 3 points. The points earned from answering x right questions would be .
Since we need at-least 45 points to win the game, so points earned from answering x questions would be greater than or equal to 45. We can represent this information in an equation as:
Therefore, you need to answer at-least 15 questions correctly to win the game.
