lys-0071 [83]

Answer:

15( b+ a) - 2(a + 0 ) = c

then

c+b = t

We could put the two together to make 15(b+a)- 2(a+0) + b = t

Where t = 8379.70

a= £249.99  b= 329.99

Step-by-step explanation:

Equal amounts are 8549.7 from 30 mowers a+b = small and large.

If we use this as an even and take away a+b at different equations we can find the answer to be 8379.70 on the 2nd equation. First equation = 8579.70

8549.7- 249.99-249.99+329.99 to equal the given year to find c in first equation and total in year = t within the above equation.
