Question

Katy paid $23 to have her haircut. She left a 20% tip. Then she bought shampoo for $6. What was the total amount that she spent?

Answer 1

`" "`
Katy paid a total of `color(red)($33.60` for her haircut and shampoo.

Explanation:

`" "`
Katy paid `color(blue)($23` for her haircut.

She offered a `color(blue)(20%` tip

Hence,

the Tip amount = `color(blue)((20/100)*23`

`rArr $4.60`

She also paid `color(blue)($6` for her shampoo.

Hence,

total amount spent by Katy will be:

`$23.00 + $4.60 + $6.00`

`$33.60`

Hence, Katy paid a total of `color(red)($33.60` for her haircut and shampoo.
