Acell phone company charges $0.05 for the first 25 text messages sent. for more than 25 text messages sent, the company
charges $0.10 for each text sent. if over 800 messages are sent, the company still charges $0.10 per text and an additional penalty
of €75 which modele the cost of any number of text messages sent?

you send:

30 text messages

25 pictures

Step-by-step explanation: The first thing we must do for this case is to define variables:

x: text messages

Y: pictures

We write the system of equations:

0.05x + 0.10y = 4

x = y + 5

Solving the system we have:

x = 30

y = 25

Step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

yes because they have the same amount of green and blur marbles.
