Answer:

$45

Step-by-step explanation:

The sale price changed from $80 to 60, then with the coupon another 25% was taken off leading it to come to a price of $45

$80 x .75 = 60

$60 x .75 = 45

(.75 is for the price of the original value that he will be paying later)

One number is four times another number. If their sum is 95, what are the numbers?
nikdorinn [45]
Let x be one number and y be the other.

#1 - Set up a system of equations.
4x = y
x + y = 45

#2 - Solve the system by substitution.
x + (4x) = 45
5x = 45
x = 9

(9) + y = 45
y = 36

The cost to print digital photos at a local store is
snow_tiger [21]
<h2>The cost is same for both the options if we purchase 27 photos</h2>

Step-by-step explanation:

   Cost of a photo at a local store is $0.25 per photo. This cost can be modeled to be linear in number of photos as C_{1}(x)=0.25x.

   Cost of photos purchased online is $0.15 per photo. However there is a shipping cost of $2.70. This can also be modeled to be linear in number of photos as C_{2}(x)=2.70+0.15x.

   Let us assume both costs are the same if we purchase n photos.

So, C_{1}(n)=C_{2}(n)

0.25n=2.70+0.15n

0.10n=2.70

n=27

∴ On purchasing 27 photos, cost for both the options is the same.
