Pine bluff middle school is having its annual spring fling dance, which will cost $400\$400$400dollar sign, 400. the student treasurer reported that the dance fund has $75\$75$75dollar sign, 75 left over from last year. each ticket to the dance costs $4\$4$4dollar sign, 4.

let t represent the number of tickets sold. write an inequality to determine how many tickets must be sold to pay for this year's dance.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
