Save you more offers a buy one/get one free item each week. customers who purchase only one of the items must pay the regular price. the limit is one deal per customer. is the relation (# sale items purchased, price) a function? why or why not? a) it is a function because the input can be either 1 or 2 items, but the output will always be the same price. b) it is not a function because the input can be either 1 or 2 items, but the output will always be the same price. c) it is a function because the input will always be the same price, but the output can be either one or two items. d) it is not a function because the input will always be the same price, but the output can be either one or two items.

The answer is A

It is a function because the input can be either 1 or 2 items, but the output will always be the same price.

According to the stated relation, (# sale items purchased, price), the input is the number of sale items purchased and the output is the price. The input values of a function can be different and have the same output value. However, a function cannot have different outputs for the same input.

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
