Answer:

60 hours

Explanation:

if $250 is for 20hrs, $750 is for x hours (let the number of hours be x)

$250=20hrs

$750=x hrs

then you cross multiply. Which will be represented as

250x= (750x 20)

Divide both sides by 250

X =750x 20/ 250

X = 15000/250

X = 60 hours

Answer: Mrs. Zech would need to work 60 hours to earn $750.
