Original Price = Final Price / (100 - Discount)
So...
OP = 360 / 100 - 0.40
OP = 360 / 0.60
OP = 600
The original price is $600.
To check, do 600 - (600 * 0.40) in a calculator. You get 600 - 240 = 360, the discounted cost.
a) 2/5(n)=6 n=15
b) 4/7(x)=16/3 x=28/3 x=9.33333 x=9 1/3
any option for b works
i hope this is right and helps
5 x 3/4 = 15/4
15/4 = 3 3/4
Step-by-step explanation:
with $4,000 invested, Jake has
8% × $4,000 = $320 annually.
in order to have annual interest $628, he has to get more interest $(628-320) = $308.
the rate should be:
308/2800 × 100%
= 308 /2800 × 100%
= 11%
