Every item in the Just a Dollar store is priced at $1.00. When Mary Jo opens the store, there is $125.50 in the cash register. When she counts the money in the cash register at the end of the day, the total is 1,058.60. If the sales tax rate is 8.5%, how many items were sold that day?
I need to make an equation and solve it. I tried 1058.60-125.50(0.085)=X, but that didn't work and then I tried 1058.60(0.085)-125.50=X and that didn't work either so im at a loss.

Step-by-step explanation:

If Jo started market with $125.5, then she won't pay tax on that cash at hand. He has probably pay the tax the previous day.

At the end of the day he counted $1058.60, this implies that the cash at hand and the sales for the day is $1058.60.

Therefore the sales for the day which he is going to pay tax on is

$1058.60-$125.50=$933.1

Therefore the sales for the day is 933.1

So he is going to pay a tax of 8.5% on the sales of $933.1

Revenue is generated on each item sold, so for every 1 dollar item a revenue of 8.5% is generated

Therefore the equation becomes

933.1=x +8.5% of x

x is the number of items

933.1= x+ 0.085x

933.1= 1.085x

Therefore x= 933.1/1.085

x=860

860 items are sold in the store

step-by-step explanation:

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
