Question

Naomi has earned $54 mowing lawns

Answer 1

Answer:

8 dollar/hr

Step-by-step explanation:

she worked 2 1/2 hrs yesterday and 4 1/4 hrs today

2 1/2 + 4/14

2+4 is 6

and 1/2+1/4 multiply 2 to both numerator and denominator of  1/2 so that the denominator of both fraction is like

it will now become 2/4+1/4 which equals 3/4

This means that she worked total of 6 3/4 hour in all yesterday and today

she is paid 54 dollar

we will need to divide 6 3/4  or written as 6.75 by 54 to find how much she earns per hour

and that would be 8

so she earns 8 dollar per hour.
