Question

Round to the nearest cent or whole number as needed. The price of a candy bar is $0.82. If the tax rate is 8%, find the total cost of the candy bar.

Answer 1

X over .82 = 8 over 100

cross multiply .82 by 8
.82×8=6.56

divide 6.56 by 100.
6.56÷100=.0656

round to 7 
.07

add .82 to .07.
.82+.07= .89

the candy bar cost $0.89
