Question

Lydia spent 4/5 of her money on a mobile phone and 2/3 of the remaining amount on a bag. She had $60 left. How much more money did she spend on the mobile phone than on the bag?​

Answer 1

Answer:

she spend $600 more on phone than on bag.

part A:

let the money she have be m,

she spent on mobile phone: $\sf m * \frac{4}{5}$ → $\sf \frac{4}{5}m$

remaining: $\sf m-\frac{4}{5}m$ → $\sf \frac{1}{5}m$

she spent on bag: $\sf \frac{1}{5}m * \frac{2}{3}$ → $\sf \frac{2m}{15}$

remaining: $\sf \sf \frac{1}{5}m - \sf \frac{2m}{15}$ → $\sf \frac{1}{15}m$

so,

$\sf \frac{1}{15}m$ = 60

m = $900

part B:

money she spent on mobile phone:  $\sf \frac{4}{5}m$  →  $\sf \frac{4}{5}(900)$  →  $720

money she spent on bag: $\sf \frac{2m}{15}$  →  $\sf \frac{2}{15} * 900$ → $120

more money she spent on mobile phone than on bag:

mobile phone cost - bag cost

720 - 120

$600
