Answer 2

Option 2 50 ≤ s ≤ 100

Option 5 She could deposit $50

Option 6 She could deposit $75

Explanation:

Let

s -----> amount of money Layla deposit into a saving account

we know that

25%=25/100=0.25

50%=50/100=0.50

so

`s\geq 0.25*200` ----->
`s\geq \$50`

`s\leq 0.50*200` ----->
`s\leq \$100`

The compound inequality is

`\$50 \leq s\leq \$100`

Verify each case

case 1) 25 ≤ s ≤ 50

The statement is false

see the procedure

case 2) 50 ≤ s ≤ 100

The statement is True

see the procedure

case 3) s ≤ 25 or s ≥ 50

The statement is false

Because is s ≤ 100 and s ≥ 50

case 4) s ≤ 50 or s ≥ 100

The statement is false

Because is s ≤ 100 and s ≥ 50

case 5) She could deposit $50

The statement is true

Because the value of s satisfy the compound inequality
`\$50 \leq s\leq \$100`

case 6) She could deposit $75

The statement is true

Because the value of s satisfy the compound inequality
`\$50 \leq s\leq \$100`
