Part A: To find the amount of the discount multiply the regular price by the amount of the discount:
80 x 20% = 80 x 0.20 = 16
The discount is $16
Part B:
20% off means she would be paying 80% of the original price ( 100% - 20% = 80%)
Multiply the regular price by 80%:
120 x 80% = 120 x 0.80 = 96
She will pay $96
20 = 10 x 10 = 100 x 2 = 200
40 = 200x2 = 400
60 = 200x3 = 600
Answer:
Number of yards per day = 20.83 yard (Approx)
Step-by-step explanation:
Assume;
Number of yards = x per day
Number of yards on 6th day = x + 8
Total yards = 133
Find:
Number of yards per day
Computation:
Total yards = 5[x] + x + 8
133 = 6x + 8
6x = 125
x = 20.83 yard
Number of yards per day = 20.83 yard (Approx)
Answer:
