Daryl is buying apples and bananas. he bought (a) pounds of apples that cost $2 per pound and (b) pounds of bananas that cost $1 per pound. write an expression that represents this situation.

Expression 2a + b represents the situation (total cost) of buying a apples and b bananas.

Solution:

Given that  Daryl is buying apples and bananas.

He bought (a) pounds of apples that cost \$2 per pound.

He bought (b) pounds of bananas that cost \$1 per pound.

Need to write an expression which represents the situation.

Cost of 1 pound of apple = 2

\text { So cost of } a \text { pounds of apple }=a \mathrm{x} \text { Cost of } 1 \text { pound of apple }=a \mathrm{x} 2=2 a

Cost of 1 pound of banana =1

\text { So cost of } b \text { pounds of banana }=b \text { x Cost of } 1 \text { pound of banana }=b \times 1=b

Total cost of apples and banana = 2a + b  

Hence, the required expression is 2a + b.

2a+ 1b

Step-by-step explanation:

Hi to answer this question we have to write an expression with the information given.

The expression is equal to the product of the pounds of apples bought (a) and the price per pound (2) plus the product of the pounds of bananas bought (b) and the price per pound (1).

Mathematically speaking:

2a+ 1b

Feel free to ask for more if needed or if you did not understand something.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
