Answer:
Part A : 2 snacks
Part B : Solution to both the inequality and the problem situation ⇒ 1 , 2
Solution to the inequality only ⇒ -4 , 3/4 , 2.3
Not a solution ⇒ 2.5
=================================================================
Step-by-step explanation:
Part A :
Janelle has $20 to spend
She spends $8 on a ticket, so , the remaining = 20 - 8 = $12
Each snack costs $4.99
So, the number of snacks =
the integer of ( 12 / 4.99 ) = integer of (2.4) = 2 snacks
Part B:
Inequality that represents this situation: 20 ≥ 8 + 4.99x
Solve for x
∴ 20 - 8 ≥ 4.99 x
12 ≥ 4.99 x
divide both sides by 4.99
∴ (12/4.99) ≥ x
∴ x ≤ 2.4048
The given options are : -4 , 3/4 , 2.3 , 2.5 , 1 , 2
So,
Solution to both the inequality and the problem situation ⇒ 1 , 2
solution to the inequality only ⇒ -4 , 3/4 , 2.3
Not a solution ⇒ 2.5
