Mr mcnall brought $562 freezer using a credit card that charges 18% annual interest if he does not make any payments or any additional charges how much will he owe after one month

Respuesta: el deberá $8.43 de interés en un mes.

Explicación paso a paso:

Regla de 3

$562 -- 100%

x --- 18%

x = 101.16

$101.16 es la cantidad de intereses que deberá en un año, pero ¿en un mes?

Para saberlo solo lo dividimos entre la cantidad de meses en un año (12)

101.16 ÷ 12 = 8.43

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
