Hannah is at the supermarket to buy carrots and potatoes. If she buys 2 pounds of carrots and 3 pounds of potatoes, it will cost
larisa86 [58]

Answer:

Potato price = $1.5 / pound ; Carrot price = $1.75 / pound

Step-by-step explanation:

Let price of carrot per pound = c

Let price of potatoes per pound = p

Given :

2c + 3p  = 8   (eqtn A)

4c + 4p = 13 (eqtn B)

Multiplying eqtn A by 2 ;

4c + 6p = 16

4c = 16 - 6p (eqtn Y)

By eqtn B ;

4c = 13 - 4p (eqtn Z)

By eqtn Y & Z ;

16 - 6p = 13 - 4p

16 - 13 = - 4p + 6p

3 = 2p

p = 3 /2

p = 1.5 [Potato price]

Putting p value in eqtn A

2c + 3 (1.5) = 8

2c + 4.5 = 8

2c = 8 - 4.5

2c = 3.5

c = 3.5 / 2

c = 1.75 [Carrot Price]

1 1/8 +5/6 =<br><br> And then subtract 1/2 from the answer
kari74 [83]
Alright so start of with solving 1 1/8+5/6

Solve and you get 1 23/24

Now to subtract you have your answer subtracted by 1/2:

1 23/24-1/2=1 11/24

And so you get 1 11/24
