Rob is saving to buy a new mp3 player. for every $13 he earns babysitting, he saves $9.on saturday, rob earned $65 babysitting. how much money did he save/

the amount of money that he saved is $45

Step-by-step explanation:

Rob is saving to buy a new MP3 player. For every $13 he earns babysitting,he saves $9. Assuming he earns $x in a week, then the amount of money that he saves would be

9 × x/13 = 9x/13

On Saturday,rob earned $65 babysitting. It means that x = 65

Therefore, the amount of money that he saved would be

(9 × 65)/13 = 585/13 = $45

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
