Standard problem

Standard

A seamstress is paid ₱35 per school uniform (piecework). How many uniforms must she finish in a 26-day month to match the ₱16,770 monthly minimum wage? Round up to a whole number.

Show step-by-step solution

Answer: 480 uniforms

$16{,}770 \div 35 = 479.14\ldots$
She cannot finish a fraction of a uniform, so she needs 480 uniforms, about 18.5 a day.

Common errors to watch for

Rounding down to 479 falls short of the target.
