Answer:$1636.4
Step-by-step explanation:
Selling price(sp)=$1800
Profit%=10%
Cost price(cp)=?
Profit%=(sp-cp)/cp x 100
10=(1800-cp)/cp x 100
Cross product
10cp=100(1800-cp)
Open brackets
10cp=180000-100cp
Collect like terms
10cp+100cp=180000
110cp=180000
Divide both sides by 110
110cp/110 = 180000/110
cp=1636.4
Cost price is $1636.4
Answer:
29%
Step-by-step explanation:
210-150/210 = 60/210 or 6/21
Now we have to find the percent out of 100 so we have to find out 100/21 to see what we have to multiply by to get to 100 so we can do the same with the 2 (numerator) so 1000/21= 4 16/21
then we have to multiply the 6 by 4 16/21 which is about 29%
