For passing Grade 8, you received a $150 gift card. You want to purchase a skateboard for $78.50 and a helmet for $32.00. a) Sales tax is 13%. What is the total sales tax? b) How much money will you have left on your gift card after you buy these items? *

a) $14.37 sales tax

b) $25.13 left on gift card

Step-by-step explanation:

Purchases: 78.50 + 32.00 = 110.50

Sales tax: 13%:

1% of 110.50 = 1.1050

1.1050 x 13 = 14.365

rounded to 2 decimal places: $14.37

Total cost: 110.50 + 14.37 = $124.87

Gift card: 150.00 - 124.87 = 25.13

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
