Hi , the answers is 0.5 kilograms.
Using the pythagorean theorem, the answer is 68.88 !
a^2 + b^2 = c^2
16^2 + 67^2 = c^2
256 + 4489 = 4745
to undo the squared, you find the square root of 4745 and its 68.88 rounded
Given:
Let baked beans be x
Let brown sugar be y
Let biscuits be z
5x + 4y + 2z = 150 - 26
5x + 4y + 2z = 124
a can of baked beens costs half as much as a packet of biscuits:
x = 1/2 * z = z/2
a packet of sugar is 3.00 cheaper than a packet of biscuits
y = z - 3
We substitute x and y with its values:
5x + 4y + 2z = 124 ; x = z/2 ; y = z-3
5(z/2) + 4(z-3) + 2z = 124
5z/2 + 4z - 12 + 2z = 124
5z/2 + 6z = 124 + 12
2(5z/2 + 6z) = 2(136)
5z + 12z = 272
17z = 272
z = 272/17
z = 16 price of a packet of biscuits.
can of baked beans : x = z/2 ; x = 16/2 = 8
packet of sugar : y = z - 3 ; y = 16 - 3 = 13
5x + 4y + 2z = 124
5(8) + 4(13) + 2(16) = 124
40 + 52 + 32 = 124
124 = 124
