PLEASE HELP!!! - 55 pts

1.) Mrs. Zech babysits for extra money.
-The job pays $250 for twenty hours of work
-She needs to make $750
How many hours of babysitting would Mrs. Zech need to work to earn the $750?

Answer 1

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 2

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

Step-by-step explanation: 250 x 3 = 750, Every 20 hours Mrs. Zech makes $250 therefore 20 x 3 = 60 hours of work.
