Since 3lb pears is $3.87 lets say that every 1lb of pears costs $1.30.
say if you were to buy 2lb on-top of the 3lb it would cost $2.60 extra, causing the total price to be around $6.50 (rounded up)

so since 5lb is $6.65, i believe that the 3lb of pears is the better buy.

For the first option:
If you can buy 3 lb of pears for $3.87 then you can buy 1 lb of pears for 3.87÷3=$1.29

Forbthe second option:
If you can buy 5 lb of pears for $6.65 then you can buy 1 lb of pears for 6.65÷5=$1.33

As we can see, it is cheaper to buy from the first seller as 1 lb of pears is 4 cents cheaper to buy than the second option. So, 3 lb of pears for $3.87 is a better buy.

inn [45]

Answer:

It took 2 hours by plane

Step-by-step explanation:

let bus is represented by x and plane is represented by y

the total distance of bus and plane will be represented by equation:

40 x + 600 y = 1320           (1)

the total time taken by bus and plane will be represented by:

x + y = 5                              (2)

solving equations (1) and (2) simultaneously:

Multiply by 40 on both sides in eq (2)  and then subtract (1) and (2)

40 x + 600 y = 1320

40 x + 40 y = 200

_______________

         560 y = 1120

               y   = 1120/ 56

               y= 2

since plane is represented by y so, the time they spent travelling by plane is 2 hours.

A rectangular park is 150 yards on one side and 125 yards on the other.
Ket [755]
So, there is a rectangular park with longer side (length) 150 yards and shorter side (width) 125 yards.

so walking around the rectangular park once is like covering the Perimeter (p) of the rectangular park.

So, lets find the perimeter of the park.
Perimeter of rectangle = 2 ( l + w)
                                    = 2 ( 150 + 125 )
                                    = 2 * 275
                                    = 550 yards

Now, walking around the park two times is like doubling the Perimeter of the rectangle. So, when Debbie walks around the park 2 times, he covers the perimeter of the rectangular field twice.

i.e. Debbie walked 2 * Perimeter
                               = 2 * 550
                               = 1100 yards

Now, If Debbie wanted to walk 1,000,000 yards, she has to walk the  rectangular park (1,000,000 / the Perimeter of the park)
         i.e.  1,000,000 / 550
             = 1818.18 times

So, 
(a) she walks 1100 yards
(b) She have to walk 1818.18 times
