Given:
Regular price = r
discount rate = 30%
coupon = $5 off any single item at the store
expression: 3(r - 0.3r) - 5
C.) 3(0.7r) - 5 represents the total cost before tax.
3(r-0.3r) - 5 ⇒ 3(0.7r) - 5
The coupon can only be used once because the problem stated any single item not every single item purchased.
Answer: 30x= T
Step-by-step explanation:
I solved this by first finding the rate of change (or the amount it changes by each day) which is 30. Then I put the variable (or X) after it which represents the number of days. Then it equals T because that’s the total amount of time spent!
Answer:
No.P=347
Step-by-step explanation:
The fence is 2768 feet long, how many posts should be placed along the fence if the adjacent distance between them is 8 feet?
How to start and end with a post the number of them (No.P) will always be the distance of the fence (f) between the adjacent distance of the posts (p) plus one

As an example we have graph 1
Answer:
A total= 0.6703125 ft²
Step-by-step explanation:
A1= 3.9× 14.3= 55.77 in²
A2=1/2 × 14.3× ( 9.6-3.9)= 40.755 in²
A total= A1+ A2= 55.77+40.755=96.525 in²
1 ft= 12 in , 1ft²= 144 in²
Atotal= 96.525÷144= 0.6703125 ft²
