Eric downloads the coupon 10% discount on any 1 item, and goes shopping at gadgets galore, where he buys a digital camera for $95 and an extra battery for $15.99. a. what is the total cost if the coupon is applied to the digital camera? b. what is the total cost if the coupon is applied to the extra battery? c. to which item should eric apply the discount? explain. d. eric has to pay 8% sales tax after the coupon is applied. how much is his total bill?

Step-by-step explanation:

A. 95*0.10=9.50

95.00-9.50=85.50

85.50+15.99=$101.49

B. 15.99*0.10=1.599

15.99-1.599=14.391

14.391+95=109.391

But it’s money, so the answer is $109.39

C. Eric should apply the discount to the digital camera because the total cost is cheaper than applying the discount to the extra battery.

D. 95+15.99=110.99

110.99*0.10=11.0990

110.99-11.099=99.891

99.891*0.08=7.99128

99.891+7.99128=107.88228

Since it is money, the answer is $107.88

step-by-step explanation:

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.
