3. At the school carnival, students sold 483 hamburgers for $4 each and 214 hot dog
for $2 each.
a. Write an equation to find how much money they took in from the sale of
hamburgers. Use the letter h to represent the unknown amount. Then solve
the equation.

Step-by-step explanation:

I think the equation should be

483 x 4 = h

1932 = h

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

the answer is here
