A scale of 1:125000 means that for any length that is on the map, the real life length is 125000 times as long. This also means that for any length in real life, the length on the map is 1/125000 times as long.
So, a real life length of 10km will be represented by a map length of 10km/125000 = 0.00008km = 8cm
I am fairly certain it’s C 1.07X since that would include both the tax and its original price
Let
x-------------> <span>the price of each cup
</span>y-------------> the price of each plate
we know that
5x+3y=28.50----------> equation 1
and
x=y-6.30--------------> equation 2
I substitute 2 in 1
5*(y-6.30)+3y=28.50---------> 5y-31.5+3y=28.5-----> 8y=60
y=7.5
x=y-6.3---------> x=7.5-6.3---------> x=1.2
the answer is
the price of each cup is $1.2
the price of each plate is $7.5
