Answer:
c
Step-by-step explanation:
Amount paid for the first book is $17.
Amount paid for the second book is 0.75 x 8 = $6
Total amount paid = $17 + $6 = $23
Total full cost of the two books = $17 + $8 = $25
Amount of discount = $25 - $23 = $2
% reduction =
Therefore, the <span>percent of the total cost of the two books reduced during the sale</span> is 8%
Answer:
<em>Interest = $3,888</em>
Step-by-step explanation:
Formula:
I = prt or I = p · r · t
what it stands for:
I = amount of interest
P = principal amount ($1,200)
R = interest rate (in years)(3% into decimal which would be .03)
T = amount of time (in years)($108)
so:
I = prt
I = (1,200)(.03)(108)
I = $3,888
Interest = $3,888
Answer:
m∠E = 38.7°
Step-by-step explanation:
If you make a drawing it will help. What you have is a right triangle where you are given the adjacent side to ∠E and the hypotenuse.
The cosine of a angle = adjacent side/hypotenuse.
Therefore cos E = 32/41
arccos (32/41) = 38.7°
