A student wrote a photography manual which she plans to sell online for $ 13 per copy. Her total expenses were $ 55. Write a lin
ear equation to show the relationship between x , the number of manuals the student sells, and y , the profit the student earns.
1 answer:
Answer:
y = 13x - 55
Step-by-step explanation:
So this is what we know
Selling price = $13 per copy
Expenses = $55
The formula for profit in this case is:
Profit = total selling price - expenses
In which y is the profit
The total selling price is 13x. x here is for the number of manuals she sells
The expenses are $55.
This then becomes y =13x - 55

if she walks 5 miles in a hour she can walk 2.5 miles in 30 minutes
Use pythagoras
d = √(Δx² + Δy²)
d = √(12-2)² + (9-4)²
d = √(10² + 5²)
d = √(100 + 25)
d = √125
d = 5√5
d = 5 × 2.236
d = 11.18
The nearest tenth is 11.2, so the distance is near to 11.2
