Answer:
2500 pence (C = 2500)
Step-by-step explanation:

From the given information, t is the number of texts so essentially you will plug in the number of texts provided (150) in the place of the variable t.

Apply the same thing to minutes, plug in the number of minutes (50) in the place of the variable m.

Now multiply the substitutes with the co-efficient.
(10*150=1500 & 20*50=1000)
Add the addends
C = 2500
Answer:
52
Step-by-step explanation:
120 x .25 = 30
120 - 30 = 90
90 x 0.2 = 18
90 - 18 = 72
72 -20 = <u>52</u>
Answer:
Step-by-step explanation:
First you need to set up the equation 2/3+1/4/1/2, and we know that there is a stratgey for dividing fractions as well. But first, we need to find the least common fator for 2/3 and 1/4 which is twelve which would be 8/12+3/12 which is 11/12 and 11/12 dividing by 1/2 is 22/12 since all you need to do is do the keep change flip method which would give you an answer of 1 10/12 or 1 5/6
