Total sales tax amount #= $ 10.40#

Cost of stereo # = $198

Sales tax # = 5.25%#

Tax amount # = 198 * (5.25/100)#

Total sales tax amount #= $ 10.40#

An estimate for the tax is #$10#.

The actual amount will probably be a bit more.

The key word in the question is 'estimate'.

This means without doing an accurate calculation, how can I get an approximate answer quickly?

The stereo costs about #$200# (very close to #$198#, just easier.)

#5.25%# can be considered as #5%# to make it easier to work with.

#5%# of #$100# is #$5#, so #5%# of #$200# is #$10#

An estimate for the tax is #$10#
