# The final cost of the certain equipment is php 3060 after successive discounts of 15% and 10% have been made on the market price. what is the original price?

4000 is the original price

step-by-step explanation:

c=cost

b=base

r=rate %

p=percentage

im using the formula

c=b-p

derive the formula p=br

c=b-br

10% is the last done, so where doing it first

3060=b-b10%

rearrange

3060=b-0.1b

(10%=0.1)

3060=0.9b

divide .9

3,400=b

or

b= 3,400

next at 15%

3,400=b-.15b

3,400=0.85b

divide by 0.85

b=4000

1  add the whole numbers first
6+\frac{5}{76}+\frac{7}{8}6+​76​​5​​+​8​​7​​
2  find the least common denominator (lcd) of  \frac{5}{76}, \frac{7}{8}​76​​5​​,​8​​7​​lcd =  1523  make the denominators the same as the lcd
6+\frac{5\times 2}{76\times 2}+\frac{7\times 19}{8\times 19}6+​76×2​​5×2​​+​8×19​​7×19​​
4  simplify. denominators are now the same
6+\frac{10}{152}+\frac{133}{152}6+​152​​10​​+​152​​133​​
5  join the denominators
6+\frac{10+133}{152}6+​152​​10+133​​
6  simplify
6\frac{143}{152}6​152​​143​​

done: )

Aahh, k, dali lng, here. pag may nakita kang dalawand term na magkaparehas and variable at ipagsama mo, tapos itranspose/ bliktarin mo ung sign ng coefficient/ number na walang 4x+7=3, ung 7 magiging -7 at ganito na ung 4x=3-7, tapos maiwan si x, kaya divide bothe sides by so x= -1
Connaissez-vous la bonne réponse?
