Toko sepatu memberi diskon 30% untuk semua barang.Jika tasya membeli sepasang sepatu dan ia membayar Rp 336.000,00 setelah mendapat diskon,harga sepasang sepatu tersebut sebelum diskon adalah
Answer:
IDR 480,000
Step-by-step explanation:
Persentase diskon = Harga lama - Harga baru / Harga lama
Harga lama = Harga sebelum diskon = x
Harga Baru = IDR 336000
Persentase diskon = 30%
Karenanya:
30% = x - 336000 / x
30/100 = x - 336000 / x
0.3 = x - 336000 / x
Cross Multiply
0.3 × x = x - 336000
0.3x = x - 336000
x - 0.3x = 336000
0.7x = 336000
x = 336000 / 0.7
x = IDR 480,000

It is the end of the semester, and the clubs at school
are recording their profits. The Science Club started out
with $20 and has increased its balance by an average
of $10 per week. The Math Club has saved $5 per
week after starting out with $50 at the beginning of the
semester.
al. Choose the equation below which represents the
balance the science club has. Let x represent the
number of weeks and y represent the balance of the
science club's account
y= 20 + 50x
y= 20 + 10x
y= 10 + 20x
y= 10 + 10x
y=50 + 5x
Y=5 + 10x
Answer:
y=20 + 10x
Step-by-step explanation:
Y=balance

Answer:
2/8 which simplifies to 0.111111
Step-by-step explanation:
Write an equation in slope-intercept form that passes through (5, -8) and runs perpendicular to y = 5/2x + 4
y= (-2/5)x-6
Step-by-step explanation:
the slope of the line perpendicular the the given line is found by the formula m1.m2= -1 hence m2= -2/5
using the slope-intercept form
y+8= -2/5(x-5) y= (-2/5)x-6

what is this(9 + 4) × (8 -7)
Answer:
13
Step-by-step explanation:
To solve this you have to add 9 and 4 first so you get 13. Next, you have to subtract 8 from 7 so you get 1. Now all you have to do is multiply 13 and 1 so you get 13 as your answer.
9 + 4 = 13
8 - 7 = 1
13 × 1 = 13
I hope this helps you :D

A camera has a listed price of $819.99 before tax. If the sales tax rate is 6.75%, find the total cost of the camera with
sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:
The answer is $875.34
Step-by-step explanation:

819.99 * 6,75% = 55.349325
Next I rounded it.
55.349325 = 55.35
Lastly, I added 819.99 plus 55.35
819.99 + 55.35 = 875.34
