Answer:
200 berlindes
Step-by-step explanation:
Vamos representar
O número total de berlindes na caixa = X
Mármores vermelhos = 20% de X
= 0.2X
Mármores amarelos = 40% de X
= 0.4X
Mármores azuis = 80
Conseqüentemente,
0.2X + 0.4X + 80 = X
Recolher termos semelhantes
80 = X - 0.2X - 0.4X
80 = X - 0.6X
80 = 0.4X
Divida ambos os lados por 0.4
X = 80 / 0.4
X = 200
Uma vez que X representa o número total de berlindes na caixa, portanto, o número total de berlindes na caixa = 200 berlindes
Answer: C. Package 3
First, find out what each cell phone package costs for 1 month by dividing the cost by however many months:
Package 1: $160 ÷ 4 = $40 for 1 month
Package 2: $128 ÷ 4 = $32 for 1 month
Package 3: $60 ÷ 2 = $30 for 1 month
Since package 3 costs the least amount of money for 1 month out of all of the other packages, that package offers the best deal. So C) Package 3 is your answer
