If you have a discount of 15% off of a purchase of 0.99$, how much money does the purchase cost after markdown? (Show work please, if you don’t show work I won’t give brainliest)

If you first start with 10% of 0.99 which is 0.099 then do 1% of 0.99 which will= 0.0099 then times the 0.0099 to get 5% which is 0.0495 then you do 0.099+0.0495 which equals 0.1485 then minus 0.1485 from 0.99 which is 0.8415

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
