Answer:
The answer is: amount of flour used for bread and brownies is same
Step-by-step explanation:
Step 1:
Assume;
Flour used for cookies = x
Flour used for bread = z
Flour used for brownies = y
Flour used for cookies = a
Step 2:
Now, for bread as mentioned flour used for bread is one fourth less than flour used in cookies therefore;
z = x - (1/4)x
z = x-0.25x
z = 0.75x
Step 3:
Now, for cookies as mentioned flour used for cookies is one third more than flour used in brownies therefore;
x = (1/3)y + y
x = 0.33y + y
x = 1.33y
Step 5:
Value of z from step 2:
z = 0.75x
now put value of x from step 3 in above equation;
z= 0.75 (1.33y)
z = (1) y
hence proved;
z = y
Answer:
$74.8
Step-by-step explanation:
step 1: apply the discount to the price
12% = .12
$79.97 X .12 = $9.5964
$79.97 - $9.5964 = $70.3736
step 2: apply tax
$70.3736 X .0625 = $4.39835
$70.3736 + $4.39835 = $74.77195
step3: round
$74.8
