Lara charges $12 per hour for babysitting. If f represents Lara's total fee after babysitting for h hours, which equations can be used to model the situation?

f= 12h , where f =  Lara's total fee after babysitting for h hours.

Step-by-step explanation:

Given: Lara charges $12 per hour for babysitting.

Charge per hour = $12

Let h= Number of hours

Total charge = (Charge per hour) x (Number of hours)

If f =  Lara's total fee after babysitting for h hours.

then, f= 12h

Hence, the required equation to model the situation : f= 12h

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
