Admission prices for a concert are $19 for adults and $11 for students. The concert will not be booked unless total ticket sales are at least $4500. Write the inequality that expresses this information. (Let the x refer to the number of adult tickets and the y refer to the number of student tickets.)

=============================================

Explanation:

x = number of adults

y = number of students

The expression 19x represents the money from all the adults while 11y represents the money from all the students (since we get $19 per adult and $11 per student).

In total, the money collected is 19x+11y dollars.

We want this total to be $4500 or larger.

So that's how we get the final answer of

37 = ending with 7

unit's digit in the cube..3

56 = ending with 6

unit's digit in the cube..2

133 = ending with

unit's digit in the cube..7
