Amy bought 0.4 kg of tomatoes for $4.00.

What is the cost in dollars per kg of tomatoes?

Answers

Answer:  The required cost in dollars per kg of tomatoes is $10 per kg.

Step-by-step explanation:  Given that Amy bought 0.4 kg of tomatoes for $4.00.

We are to find the cost in dollars per kg of tomatoes.

We will be using the UNITARY method to solve the given problem.

The cost of 0.4 kg of tomatoes = $4.00.

Therefore, the cost of 1 kg of tomatoes is given by

\$(4.00)/(0.4)=\$(40)/(4)=\$10.

Thus, the required cost in dollars per kg of tomatoes is $10 per kg.
if 0.4 kg cost 4. 0 dollar
than 1.kg will cost x dollar

x = (1 * 4)/0.4 = 10 dollars

1 kg tomatoes cost 10 dollars

A jewelry store is having a going-out-of-business sale. All merchandise is marked 40% off the regular price. The regular price of a watch is $59.95 what is the amount of the discount and the sale price

Answers

Answer:

$35.97

Step-by-step explanation:

the regular price is 59.95

40% discount so

let's say the price now is x and i am gonna do fractions

x/59.95 = 40%/100

100 x X = 100x  

59.95 x 40 = 2398

i divide 2398 by 100 which equal 23.98

40% is 23.98 and then i do 59.95 - 23.96 = 35.97

George found that he blinked 85 times in 15 minutes. At this rate, how many seconds passed during 51 blinks

Answers

85 / 5 = 15
15 / 5 = 3

15 / 3 = 5
3 / 3 = 1

Therefore, he blinks 5 times a minute.  

60 / 5 = 12
5 / 5 = 1

Therefore, he blinks once every 12 seconds. 

51 / 1 = 51
 
     51
 X 12  
= 102
+ 510
= 612

Therefore, 612 seconds passed during 51 blinks.
