Answer:
Solution,
CP of a bicycle=$3000
Marked up=40%
Now,
→40% of $3000
→40/100x$3000
→$1200
→$3000+$1200=$4200
Again,
Discount(d)=30%
→30%of $4200
→30/100x$4200
→$1260
Hence, the discount price of the bicycle is $1260
Step-by-step explanation:
Answer:
m = 686.
Step-by-step explanation:
Direct variation :
m= kl^3 where k is a constant.
m = 250 when l = 5, so
250 = k *(5)^3
k = 250 / 125 = 2
So the equation of variation is m = 2l^3.
When l = 7:
m = 2 * (7)*3
= 2 * 343
= 686.
