Hailie recently had her hair cut.  The hair cut was $15.25 and her mom tipped the hair stylus 15%.  What was the total cost?  Round to the nearest hundredth.

$17.54

Step-by-step explanation:

Total cost:

Cut = $15.25 + 15% of $15.25.

1. Determine the 15% of 15.25

10% = $1.525 (you move the decimal over to the left once)

5% = 1.525/2 = $.7625

Add the 2 values together

$1.525 + $.7625 = $2.2875 - 15%

2. Add the Total Cost of the Cut and the tip together

$15.25 + $2.2875 = $17.5375

3. Round the answer to the nearest hundredth

$17.5375 turns into $17.54

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
