Answer:
The expression that can be used to determine the final cost of the game is
1.06(0.88 y) ⇒ (C)
Step-by-step explanation:
- If the price of an item is discounted, that mean its new price will be less its initial price
- The taxes on item, makes its new price greater than the initial price because tax is add
Let us solve the problem
∵ Ella purchased a game that was on sale for 12% off
→ That means the new price will (100% - 12%) of the initial price
∵ y represented the initial price of the game
→ Multiply y by (100% - 12%) to get the new price
∴ The new price = y (100% - 12%)
∴ The new price = y (88%)
→ Change 88% to normal number by divide it by 100
∴ The new price = y ()
∴ The new price = 0.88 y
∵ The sales tax in her county is 6%
→ That means the final cost will be (100% + 6%) of 0.88 y
∴ The final cost = (100% + 6%) × (0.88 y)
∴ The final cost = 106% × (0.88 y)
→ Change 106% to normal number by divide it by 100
∴ The final cost = × (0.88 y)
∴ The final cost = 1.06(0.88 y)
The expression that can be used to determine the final cost of the game is 1.06(0.88 y)
Answer:
Part 1) The value of y=6
Part 2) ED=36, DB=36 and EB=72
Step-by-step explanation:
In this problem we know that
ED=DB -----> equation A
EB=ED+DB -----> equation B
The point D is the midpoint ED
see the attached figure to better understand the problem
step 1
Find the value of y
Substitute the given values in the equation A
solve for y
step 2
Find the value of ED,DB and EB
substitute the value of y
Remember that
ED=DB
therefore
Find the value of EB
EB=ED+DB
