Tammy bought some rings and bracelets for her friends. The price of each ring was $2.90 while the price of each bracelet was $14.20. For every 7 bracelets bought, she was given one such ring for free. After receiving the free rings, the number of rings was ¹₄ of the number of bracelets bought. If Tammy paid a total of $3250.40, how much more did she pay for the bracelets than the rings?

Bracelets	Rings
4x7	1x7
Bought	Free	Bought
7x4	1x4
28 u	4 u	3 u

	Bracelets	Rings
	Bought	Free	Bought
Number	28 u	4 u	3 u
Value	$14.20	0	$2.90
Total value	397.6 u	0	8.7 u

The number of bracelets bought is the repeated identity. Make the number of bracelets bought the same.  LCM of 4 and 7 is 28.

Cost of the bought bracelets
= 28 u x 14.20
= 397.6 u

Cost of the bought rings
= 3 u x 2.90  
= 8.7 u

Total cost of the bought items
= 397.6 u + 8.7 u
= 406.3 u

406.3 u = 3250.40

1 u = 3250.40 ÷ 406.30 = 8

Amount that she paid more for the bracelets than the rings
= 397.6 u - 8.7 u 
= 388.9 u
= 388.9 x 8
= $3111.20

Answer(s): $3111.20
