Answer:
Randy can make 42 snow cones.
Step-by-step explanation:
28 divided by 2/3 = 42.
Answer:
Step-by-step explanation:
-5x-4y=-4 ...(1)
25x+ 20y = 20 ....(2)
multiply (1) by -5 you have : 25x+ 20y = 20 ....(2) same equation , same line
so : The system has infinitely solutions.
we know that
In a quadratic equation of the form 
the discriminant is equal to
if 
-------> the equation has two real number solutions
if 
-------> the equation has one real number solution
if 
-------> the equation has two complex number solutions
In this problem we have
so
substitute in the formula
----> the equation has two real number solutions
therefore
<u>the answer is</u>
the equation has two real number solutions
Let
x = base pay per month
y = commission per $1 of sales
Then the monthly pay for selling $100 of merchandise is
P = x + 100y
In one month, Alyssa earned $388 for selling $400 worth of merchandise.
Therefore
x + 400y = 388 (1)
In another month, she earned $520 for selling $1000 worth of merchandise.
Therefore
x + 1000y = 520 (2)
Subtract (1) from (2).
x + 1000y - (x + 400y) = 520 - 388
600y = 132
y = 0.22
From (1), obtain
x = 388 - 400y = 388 - 400*0.22 = 300
When Alyssa sells $3300 worth of merchandise, she earns
300 +0.22*3300 = $1026
Answer: $1026
