To make one cheese sandwich, Tina uses one bread roll and two cheese slice Pack of 15 bread rolls - £1.91
Pack of 20 cheese slices - £2.23

She is going to buy enough packs to have exactly twice as many cheese slices as bread rolls make more than 100 cheese sandwiches.
Work out the least amount she can spend.

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
