Answer:
£1.80 is the price per kilogram of the apples
Step-by-step explanation:
Here, x represents the number of apples per kilogram and y represents the number of pears per kilogram.
As per the statement:
Julie buys 2kg of apples and 7kg of pears £12.70.
⇒[tex]2x+7y = 12.70[/tex] ....[1]
It is also given that the pears cost £1.30 per kilogram
⇒y =£1.30
Substitute in [1] we have;
⇒[tex]2x+7 \cdot 1.30 = 12.70[/tex]
⇒[tex]2x+9.10= 12.70[/tex]
Subtract 9.10 from both sides we have;
⇒[tex]2x= 3.60[/tex]
Divide both sides we have;
x =£1.80
Therefore, £1.80 is the price per kilogram of the apples
