Your company recently made a purchase of 25 identical tables. The purchase price after adding 5 percent sales tax was 1,706.25.

ELEN [110]

If c = the cost of one table, the cost of all 25 tables before sales tax is 25·c

Since the sales tax is 5%, or 0.05, the sales tax for 25 tables is 25·c·0.05

Adding the sales tax to the original cost of the 25 tables can give you:
25·c + 25·c·0.05 = 1706.25
1.05·25·c = 1706.25
26.25·c = 1706.25
c = $\frac{1706.25}{26.25}$ = 65

so the refund for 5 tables would be 5*65 = $325

If A = 6 B = 9 C = 15 Then what is D equal to?

Semmy [17]

A = 6
B = 9
C = 15
D = ?

From A to B, 6 + 3 = 9
From B to C, 9 + 6 = 15
From C to D, 9 + x = ?

The first time, you added 3, for the second time, you added three to the three you are adding, making it 6. So for x, x = 6 + 3, which = 9

9 + 9 = 18

D = 18 should be your answer

hope this helps
