rope 1.98 cm long was cut into parts so that one part turned out to be 20% longer than the other part what is the length

shorter part: 0.9 cm   ||   longer part = 1.08 cm

Step-by-step explanation:

let one rope be x

other rope then will be x * 120% = 1.2x

1.2x + x =  1.98

2.2x = 1.98

x = 1.98/2.2

x = 0.9 cm

then the other rope will be 1.2(0.9) = 1.08 cm

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
