Question

Tilly and Lilly worked together on a job. Tilly earned twice as much as Lilly, and together they earned $510. How much did they each earn?

Answer 1

Answer:

Lilly earns $170 and Tilly earns $340

Step-by-step explanation:

let Lilly earn $x.

since Tilly earns twice as much as Lilly, she earns $2x.

together, they earn $510.

therefore,

x+2x = 510

3x = 510

x= 170

2x= 170 x 2

2x= 340

Lilly earns $170 and Tilly earns $340.
