Janice bought 28 apps for her phone that, altogether, used 1,348 mb of space.
a. if each app used the same amount of space, about how many mb of memory did each app use? show how you estimated.
b. if half of the apps were free and the other half were $1.99 each, about how much did she spend?

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 =

                                               = 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

just needed some points but try socratic

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
