PLZZZ HELP!

Math Problem: A store is having a sale where everything is discounted by 30%. Find the original cost if a customer buys an item that was on sale at $255.5.

365

Step-by-step explanation:

The discount is 30 %

That means we pay 70 %

original price * 70% = 255.50

Change to decimal form

original price * .70 = 255.50

divide each side by .70

original price * .70/.70 = 255.50/.70

original price =365

answer:

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
