Represent small door with S and large with L

From the question, we understand that;

So, we have that


Required
Determine the number of Large doors that can be cut from the board
To do this, we simply divide the size of the board by the size of the large cabinet
i.e.


Convert feet to inches



Get the integer part of the decimal

Hence:
3 large doors can be gotten from the board
Number of pounds of macadamia nuts is 8 pounds and number of pounds of almonds is 4 pounds.
<u>Step-by-step explanation:</u>
Step 1:
Given total pounds of mixture = 12 pounds, cost of macadamia nuts per pound = $9, cost of almonds per pound = $5.25, total cost of mixture per pound = $7.75.
Let number of pounds of macadamia nuts be x and number of pounds of almonds be 12-x.
Step 2:
Form an equation using the above information.
⇒ 9x + 5.25 (12-x) = 12 × 7.75
⇒ 9x + 63 - 5.25x = 93
⇒ 9x - 5.25x = 30
⇒ 3.75x = 30
⇒ x = 8
Number of macadamia nuts is 8 pounds.
Step 3:
Calculate number pounds of almonds
⇒ Number of pounds of almonds = 12 - x = 4 pounds.
Answer:
B 10% off sale, with a total price to pay of 756
Step-by-step explanation:
Retail price (Rp) = $800
Taxes (T) = 5%
- Offer A $75 instant rebate
Total price A (TA) = Rp - 75 + (Rp - 75) 5%
TA = 800 - 75 + (800-75) 5%
TA = 725 + 725 5%
725 5% = 725*5/100 = 36.25
TA= 725+36.25 = $761.25
Total price B (TB) = RP - RP 10% + (RP - RP 10%) 5%
TB = 800 - 800 10% + (800 - 800 10%) 5%
800 10% = 800*10/100 = 80
TB = 800 - 80 + (800 - 80) 5%
TB = 720 + 720 5%
720 5% = 720*5/100 = 36
TB = 720 + 36 = $756
- Offer C 5% off sale plus store pays sales tax
store pays sales tax means Walden's family will not need pay for taxes
Total price C (TC) = RP - RP 5%
TC = 800 - 800 5%
800 5% = 800*5/100 = 40
TC = 800 - 40 = $760
- Offer D a “no tax” sale—the store pays the tax
Means that Walden's family will need pay just the retail price
TD = $800
The beast deal is from the store B
