During the Christmas season, a store offers a sale. You buy one item for the regular price then you get 60% discount on a second

Lelu [443]

Answer:

24%

Step-by-step explanation:

Given: Regular price of two item is $30 and $20.

60% discount provided on second item.

Now, lets find out discount provided on second item.

∴Discount provided = $\frac{60}{100} \times 20 = \$ 12$

Amount paid for second item = Regular price - discount provided

∴Amount paid on second item= $20 - 12= $8$

Total amount paid for two item= Regular price of first item + discounted price of second item.

∴Total amount paid for two item= $30+8= \$ 38$

Next, lets find out the percent of reduced total cost of two item.

$\frac{reduced\ amount}{total\ regular\ price} \times 100$

$\frac{12}{50} \times 100 = 24\%$

∴ By $24\%$ the total cost of two item reduce during sale.

On a partly cloudy day, Derek decides to walk back from work. When it is sunny, he walks at a speed of s miles/hr (s is an integ

Setler [38]

Answer: $\frac{1}{7}$

Step-by-step explanation:

Given

sunny day speed= s mph

Rainy day speed=s+1 mph

Derek average speed =2.8 miles/hr

s<2.8<s+1

so on sunny day speed must be 2 mph

and on rainy day speed must be 3 mph

$v_{avg}=\frac{distance}{time\ taken}$

Let x be the distance traveled in sunny and y be the distance traveled in rainy weather

$2.8=\frac{x+y}{\frac}{x}{2}+\frac{y}{3}}$

Let $\frac{x}{y}=z$

$2.8=\frac{z+1}{\frac{z}{2}+\frac{1}{3}}$

$z=\frac{1}{6}$

Fraction of distance traveled on sunny weather

$\frac{x}{x+y}=\frac{z}{z+1}=\frac{1}{7}$
