Joan received $17 and 94 cents ($17.94)
$14.20 + $7.86= $22.06 (her total)
$20+$20= $40 (how much she paid with)

Answer:
q > 4
Step-by-step explanation:
Step 1: Write inequality
7 < 4q - 9
Step 2: Solve for <em>q</em>
<u>Add 9 to both sides:</u> 16 < 4q
<u>Divide both sides by 4:</u> 4 < q
Here, we can see that any number greater than 4 will work. So even 23573489079357 would work, as long as it is greater than 4.
Answer:
120 kg of 30% fat-content chocolate and 30 kg of 40% fat-content chocolate.
Step-by-step explanation:
We are given that a candy distributor needs to mix a 30% fat-content chocolate with a 40% fat-content chocolate to create 150 kilograms of a 32% fat-content chocolate.
Let the amount of 30% fat-content chocolate be 'x' and the amount of 40% fat-content chocolate be 'y'.
So, according to the question;
x + y = 150 ------------ [equation 1]
and 





x = 120 kg
Now, putting the value of x in equation 1, we get;
x + y = 150
120 + y = 150
y = 30 kg
Hence, 120 kg of 30% fat-content chocolate and 30 kg of 40% fat-content chocolate.
