Decide whether the triangles are similar. If so, determine the appropriate expression to solve for x. A: The triangles are not similar; no expression for x can be found B: ΔABC ~ ΔDEF; x = r * w/u C: ΔABC ~ ΔEFD; x = r * w/u D: ΔABC ~ ΔEFD; x = r * w/z

I believe that those two triangles are not similar, there's no expression for x -- option 1

RM 687.3

Step-by-step explanation:

Number of members = 257

Each member makes = RM 25

So, total money = 257×25= RM 6425

1- 45 % of 6425 = 45 /100 × 6425=RM 2891.25

So, RM 2891.25  was spent for the year-end banquet. Hence remaining money after this expenditure = 6425-2891.25= RM 3533.75

2- 65 % of this remaining money = 65 /100 × 3533.75= RM 2296.45

So, RM 2296.5 were spent on souvenirs. Hence remaining amount = 3533.75 - 2296.45 =  RM 1237.3

3- Out of this remaining money RM 550 were spent for club jersey booking fees.

So, amount left = 1237.3 - 550 = RM 687.3
