Step-by-step explanation:
Step-by-step explanation:
Sp = rs 800
loss = 10%
Cp = ?
we know that,
cp= sp×100÷ 100-L%
= 800×100÷100-10
= 80000÷90
= 888.89#
Answer:
Total= 7896 points
Step-by-step explanation:
Method 1: 658 x12 = 7896 (in most cases you'd simply use a calculator to instantly solve or could use the 2 stepped multiplication method)
Method 2: 658x10= 6580 658x2=1316
therefore, 6580+1316=7896 ( this method is extremely useful for certain values since its simpler)
