Please help me with this question

$13.50

Step-by-step explanation:

m = 13.50$

Step-by-step explanation:

26.50 + m = 40

m = 40 - 26.50

m = 13.50$

what is the starting amount? the question is not clear sorry.

step-by-step explanation:

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
