Question

Can some one please help me

1.Wanyne brought an engagement ring for Tracey.
The total cost of the ring was £420 PLUS VAT at 17 1/2%

please I need your help

Answer 1

if we want to calculate the full prize we need to calculate how much the tax was:

420* 17
`(1)/(2)`%=420*
`(175)/(1000)`=420*
`(7)/(40)`=21*
`(7)/(2)`=73.5


so this is how much the tax was.

and the full prize is the cost of the ring and the tax: 420+73.5=493.5

so that's how much the buyer will pay
