Question

Problem situation:

Janelle is at the movie theater and has $20 to spend.
She spends $8 on a ticket and wants to buy some snacks. Each snack costs $4.99.
How many snacks, , can Janelle buy?

Inequality that represents this situation:
20≥8+4.99

Drag each number to show if it is a solution to both the inequality and the problem situation, to the inequality only, or if it is not a solution.

Answer 1

Explanation:

Solution to BOTH the inequality and the situation

1 and 2

Solution to the inequality ONLY

2.3 and 3/4

NOT a solution

2.5

Answer 2

FOR BOTH : 1 AND 2

FOR ONLY INEQUALITY : -4 / 2.3 / 3/4

FOR NOT A SOLUTION : 2.5

Explanation:

I SUBSTITUTED THE 6 NUMBERS AND SOLVED THE EQUASION.

FIRST, FOR FRACTIONS AND DECIMALS, WE CANT BUY A THING WITH PART OF IN SO THEY CAN BE EITHER IN ONLY INEQUALITY OR NOT A SOLUTION.

2.3 AND 3/4 CAN BE A SOLUTION ONLY WITH INEQUALITY.

-4 CAN BU USED IN THE INEQUALITY BUT ITS A NEGATIVE NUMBER NOT A WHOLE NUMBER (WHOLE NUMBERS ARE FROM 1 TO INFENITY)

BUT 2.5 CANT BE BECAUSE IT GIVES US A NUMBER GREATER THAN 20

IN ANOTHER SIDE, 1 AND 2 CAN BE USED BOTH IN INEQUALITY AND IN REAL LIFE.
