5.1% < 0.51 please help been working on this all day I really need help

WITCHER [35]

You can write any decimal as a precent by moving the decimal 2 places to the right so
0.51 = 51%
5.1% < 51%
5.1% < 0.51

or, any precent can be written as a decimal by moving the decimal points two point to the left so
5.1% = 0.051
0.051 < 0.51
5.1% < 0.51

One cell phone company charges a $76 sign-up fee and $40 per month. Another cell phone company charges $136 sign-up fee and $20

WARRIOR [948]

Answer:

The cost would be same after 3 months.

Step-by-step explanation:

Given that:

Charges of first company;

Per month charges = $40

Let,

x be the number of months

y be the total cost.

y = 40x + 76 Eqn 1

Charges of second company;

Per month charges = $20

y = 20x + 136 Eqn 2

For same cost,

Eqn 1 = Eqn 2

40x + 76 = 20x + 136

40x-20x = 136 - 76

20x = 60

Dividing both sides by 20

$\frac{20x}{20}=\frac{60}{20}\\x=3$

Hence,

The cost would be same after 3 months.
