Answer:
A) 61.68
Step-by-step explanation:
This is an exponential decay of 0.875. The way to know that is to get that is
(Pick a random number and divide by the number to the left of it) From there, there is a 12 hour difference from 7 am to 7pm! Divide 306.25/0.875 and divide it by 0.875 by the answer of that each time 12 times. The exact answer is 61.68402914
The answer is d : 1/2x + 2
9/10 is greater than 11/15
Answer:
0.428x
Step-by-step explanation:
The price of a smart phone is "x" and is discounted 40% for a special promotion.
Step 1
The price after the discount is:
40% of x
= 40x/100
= 0.4x
Step 2
We calculate the exact amount the sales tax is.
You must also pay 7% sales tax on this purchase.
= 7% × 0.4x
= 7/100 × 0.4x
= 0.028x
Step 3
The final price for this purchase is calculated as:
0.4x + 0.028x
= 0.428x
Hence, the final price for this purchase is 0.428x
K + 26 = 61
Substract 26 on each side of the equation
K + 26 - 26 = 61 - 26
K = 61 - 26
