Answer/Step-by-step explanation:

i. No. of hours Martine works per week = 33.5 hours

If she does this for 36weeks in a year, she works the following hours in a year:

33.5 hrs × 36 weeks = 1,206 hours

Rounding of to 1 significant figure (first non-zero digit counting from left to right is the first significant figure) = 1,000 hours

Thus:

33.5 × 36 = 1,000

ii. Martine earns £263 per week, in a year (36 weeks), she'd earn:

263 × 36 = 9,468 ≈ £10,000 (rounded to 1 s.f)

iii. Overtime = £8.35 per hour

To save to pay £900 for a holiday, she needs to do the following number of overtime:

900 ÷ 8.35 = 107.784431 ≈ 100 hours (rounded to 1 s.f)
