Janice bought 28 apps for her phone that, altogether, used 1,348 MB of space.

Answer 1

Answer:

a) 48.143 MB

b) Money Janice paid is $27.86

Step-by-step explanation:

given,

Janice bought 28 apps which used 1,348 MB

a) memory used by each app

each app is of equal memory

now, 28 apps use memory = 1348 MB

        memory used by 1 app = $\dfrac{1348}{28}$

                                               = 48.143 MB

b) half app are free and half apps are chargeable with $1.99 each

money he spend on app = $1.99 × 14

                                         = $27.86

Money Janice paid is $27.86
