Answer:
A. 40.18
B. 42.80
Step-by-step explanation:
A. To find the discount price of an item multiply the price by the percentage you pay. Its discounted 20% meaning you pay 80%. Then the price of the coat is 0.8(50.22) = 40.18.
B. The sale price of a shirt is 25.68. The original price as reduced by 3/5. The original price is equal to 25.68 = 3/5x. Solve for x by multiplying by the reciprocal. 25.68 ( 5/3) = x. 42.8 = x.
Given:
x = number of hours
y = total number of pages
70 = number of pages already read
30 =number of pages read per hour
y = 30x
70 = 30x
70/30 = 30x/30
2 1/3 = x
You read 70 pages within 2 hours and 20 minutes.
y = 30x
y = 30(3)
y = 90
An additional 90 pages have been read after another 3 hours.
Total pages read.
y = 30(2 1/3) = 70 pages
y = 30(3) =<u> 90 pages</u>
160 pages within 5 hours and 20 minutes.
