Answer:
Unit price of brand 'A' = $ 0.104
Unit price of brand 'B' = $ 0.1076
One should buy brand 'A' since it less costly.
Step-by-step explanation:
The given data are :-
Brand 'A' has 12 forks which costs $ 1.25.
Brand 'B' has 25 forks which costs $ 2.69.
We have to calculate unit price of each brand and find the best brand to buy according to the unit price.
First calculating the unit price of brand 'A'.
∵ 12 forks costs a total price of $1.25.
∴ 1 forks will cost = $ 
= $ 0.104
Similarly we can calculate the unit price of brand 'B'.
∵ 25 forks cost a total amount of $2.69
∴ 1 forks cost = $ 
= $ 0.1076
Here we can see that unit price of brand 'A' is less than unit price of brand 'B'. So to buy the brand 'A' forks will be productive.
Answer:
20
Step-by-step explanation:
Triangle = 10
circle = 5
square = 4 (half square = 2)
10 + 5 x 2 =20

Each of the problems asks you to a similar idea: get a common denominator with the fractions and then subtract.
Problem 1: 28 3/8 - 19 5/6
The factors of 8 are 2, 2, and 2. The factors of 6 are 2 and 3. We take one two that's repeated, two more twos from 8, and a 3 for the common denominator. So, 2 * 2 * 2 * 3 = 24 is the lowest common denominator (LCD).
Now change the fractions to the common denominators
3/8 = ? / 24 We go from 8 to 24 multiplying by 3, so 3 multiplied by 3 is 9.
5/6 = ? / 24 We go from 6 to 24 multipling by 4, so 5 multiplied by 4 is 20.
Then,
28 3/8 - 19 5/6
= 28 9/24 - 19 20/24 <----use common denominators
= 27 33/24 - 19 20/24 <--- borrow from the whole number
= 8 13/24 <---- subtract whole numbers and fraction numerators
Problem 2 works similarly to problem 1, with an LCD of 15.
18 2/5 - 9 13/15
= 18 6/15 - 9 13/15
= 17 21/15 - 9 13/15
= 8 8/15
Thus the differences are 8 13/24 (1st) and 8 8/15 (2nd).
Answer: Ksh 6144
Step-by-step explanation:
On Thursday, a fruit vendor bought 1948 oranges on a Thursday and sold 750. The number of oranges left will be: = 1948 - 750 = 1198
On n Friday, he sold 240 more oranges than on Thursday. This means the number of oranges sold is: = 240 + 750 = 990.
The number for f oranges left will then be: = 1198 - 990 = 208
On Saturday, he bought 560 more
oranges, the total oranges that the vendor has now will be:
= 208 + 560 = 768
Since sold all the oranges he had at a price of Ksh. 8 each, the amount if money made will be:
= Ksh 8 × 768
= Ksh 6144
The vendor made Ksh 6144
