Group A
Money spent by Person 1 = £500
Money spent by Person 2 = £600
Money spent by Person 3 = £900
Money spent by Person 4 = £450
Sum of money spent by group A = £2,450
Average money spent by group A =
⇒ Average money spent by group A = £612.5
Group B
Money spent by Person 1 = £700
Money spent by Person 2 = £500
Money spent by Person 3 = £680
Money spent by Person 4 = £500
Sum of money spent by group B = £2,380
Average money spent by group B =
⇒ Average money spent by group B = £595
Hence, Group B had lower average spend.
The expression can represent the value of x in terms of R, m, n and k after rearranging.
<h3>What is an expression?</h3>It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The expression is:
Square both side:
16m² x n = R²k³
x = (R²k³)/(16m²n)
The above expression represents the value of x in terms of R, m, n and k.
Thus, the expression can represent the value of x in terms of R, m, n and k after rearranging.

Considering it's critical points, it is found that the least possible degree of the polynomial graphed above is of 4.
<h3>What are the critical points of a function?</h3>The critical points of a function are the values of x for which:
In a graph, they are the turning points, and if a function has n critical points, the least possible degree is of n + 1.
In this problem, the function has 3 turning points, at x = -3, between x = -3 and x = 3, and at x = 3, hence the least possible degree of the polynomial graphed above is of 4.
