Answer:

Ok, I can see only a) to c)

a) Lucy spent the most time reading.

b) 20 minutes.

c) 22 minutes.

Step-by-step explanation:

Reason for b):

First convert hours to minutes.

1 hour = 60 minutes

4 hours = ?

4 × 60 = 240 minutes.

Homework is 30°

Total in the pie chart is 360° so:

30/360 × 240 mins = 20 mins

Answer is Zac spent 20 minutes to do his homework.

Reason for c):

Watching TV:

Zac: 135°

Lucy: 102°

Zac:

135/360 × 240 minutes = 90 minutes

Lucy:

102/360 × 240 minutes = 68 minutes

To find how many minutes Zac spent watching TV than Lucy:

90 minutes - 68 minutes = 22 minutes.

In a certain store, the regular price of a refrigerator is$600. How much money is saved by buying this refrigeratorat 20 percent
Ira Lisetskai [31]

Correct option is A. Money saved is  ′ $6 ′ .

Given

Regular price of the refrigerator = $600

i) Buying the refrigerator at 20 percent off regular price

Final Discount in this case = 20% (Regular price of the refrigerator)

= 20 / 100 × 600

​= $120

ii)  Buying it on sale at 10 percent off regular price and an additional 10 percent off sale price

Discount for the sale = 10% (Regular price of the refrigerator)

=  10/100  × $600

= $60

Sale price of the refrigerator = Regular price of the refrigerator − Discount for sale

= $600 − $60

= $540

Final Discount in this case = 10% (Sale price of the refrigerator)

= 10/100​  × $540

= $54

Money saved if we buy as (case−i) = (Final Discount in (case.i)) − (Final Discount in (case.ii))

= $60 − $54

= $6

Therefore, Money saved is  ′ $6 ′ .
