Rodrigo buys a jacket on sale for 1/4 off the original price of $80 he has a coupon for an additional 10% off. How much does Rodrigo have to pay for the jacket?
A. $18.00
B. $49.00
C. $52.00
D. $54.00

$54

Step-by-step explanation:

If there is a sale for 1/4 off we need to take 1/4 of $80 (.25*80) to find out how much we have to take off of the jacket for the sale.

1/4 of 80 is 20

Then we have to subtract 20 from 80 since we get $20 off not the jacket for $20

80-20=60

Now we take 10% of 60 (.1*60) which is $6 so again we subtract 60-6 and get $54 for the jacket

Let me know if that was confusing in the comments and i can try to explain

the answer is ! ?

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
