The jewelry center bought a pair of earrings for $250. They are going to mark the price of the earrings up 32.5%. How much will they sell the earrings for?

$331.25

Step-by-step explanation:

Given:

The jewelry center bought a pair of earrings for $250

They are going to mark the price of the earrings up 32.5%

Question asked:

How much will they sell the earrings for ?

Solution:

Cost price of a pair of earrings =  $250

Mark up value = 32.5% of $250

                        =

Now, we can find selling price of a pair of earring by simply adding the cost price and the mark up value.

Selling price = cost price + mark up value

                     = 250 + 81.25

                     = $331.25

Thus, they sell the earrings for  $331.25

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.
