Answer 1

d) 11

Explanation:

Forming the equation,

→ 75.26w + 220.39 = 1028.25

Now the value of w will be,

→ 75.26w + 220.39 = 1028.25

→ 75.26w = 1028.25 - 220.39

→ 75.26w = 807.86

→ w = 807.86/75.26

→ w = 10.73425

→ [ w = 11 weeks ]

Hence, the answer is 11 weeks.

Answer 2

• D. 11 weeks

Explanation:

Let the number of weeks Riley need to work is x.

She has $200.39 and will save $75.26 for x weeks to get $1028.25 total.

Set this as equation:

• 75.26x + 200.39 = 1028.25

Solve it for x:

• 75.26x = 1028.25 - 220.39
• 75.26x = 807.86
• x = 807.86/75.26
• x = 10.73 ≈ 11 (rounded to whole number)

Correct choice is D
