1.Erve borrows money to buy a new PS5 for $400 at a simple interest rate of 5%. He writes the equation t = 400 + (0.5 x 400) to represent the amount of money he will need to pay back after one year. Is Erve’s equation correct? Explain your answer and determine how much money Erve will need to pay back after one year.

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

this answer is !

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
