Answer:
Her first coupon ti be used is $50 off a purchase above $300
Final purchase price= $340
Step-by-step explanation:
Marie has two coupons
one for a 15% discount and one for $50 off any purchase above $300.
The stores allow the two coupons to be combined and she spends a total of $450.
Her first coupon ti be used is $50 off a purchase above $300.
So Marie have $400 now
15% off $400= 400-(0.15*400)
15% off $400 = 400-60
15% off $400 =$ 340

Answer:
<u>The width of the top surface of the desk is 1.4 feet.</u>
Step-by-step explanation:
1. Let's review all the information given for solving this question:
Length of the top surface of a desk = 5.6 feet
Width of the top surface of a desk= x
2. Let's find the width of the top surface of the desk
Length of the top surface of a desk = Four times the width
5.6 = 4x
5.6/4 = 4x/4 (Dividing by 4 at both sides)
1.4 = x
<u>The width of the top surface of the desk is 1.4 feet.</u>
Answer:
There are 4 ounces of Fiber X cereal in the mix
Step-by-step explanation:
Lets n be the amount of ounces of Fiber X in the mix. Since there are a total of 12 ounces in the mix, then, on terms of n, there are 12-n ounces of Fiber Max on it.
Since 65% of the mix is Fiber, then there are 12*0.65 = 7.8 ounces of Fiber. We can also obtain this value if we take the proportions of Fiber in each cereal of the mix (in terms of n), so that we can obtain the true value of n
we have
7.8 = n *0.55 + (12-n)*0.7 = 0.55n + 8.4 -0.7 n = 8.4-0.15n
Therefore
0.15 n = 0.6
n = 0.6/0.15 = 4
As a consecuence, there are 4 ouces of Fiber X cereal in the mix.
