Answer:
$10.56
Step-by-step explanation:
Cross multiply and divide!
if the total cost is $176, multiply by the % of sales tax and divide by 100 (100%)
176 multiplied by 6% = 1,056
1,056 divided by 100% = $10.56
20x-1000 +4000 = 60x
20x-60x= -4000 +1000
-40x= -3000
x= -3000/-40
75 The mix will be 75 lbs
And $20 coffee will be 75 -50 = 25lbs
Cost of 2 1/2 yards= $15
cost of 1 yard=?
cost of one yard= 15/(2 1/2)
=15/5/2
=15/5*2
=3*2
=$ 6
so the cost of fabric for one yard will be $6
