Alisiya [41]

Answer: They will charge same amount for 360 minutes of calls.

Step-by-step explanation:

A phone company offers two monthly plans plan A cost $9 Plus And additional 0.12 $ for each minute of calls. Plan B cost $27 plus an additional $0.07 for each minute of calls

For what amount of calling do the two plans cost the same?

Let the each minute of calls be 'x'.

So, for plan A would be

plan A cost $9 Plus And additional 0.12 $ for each minute of calls is expressed as

y_1=9+0.12x

Plan B cost $27 plus an additional $0.07 for each minute of calls is expressed as

y_2=27+0.07x

According to question, it becomes,

y_1=y_2\\\\9+0.12x=27+0.07x\\\\0.12x-0.07x=27-9\\\\0.05x=18\\\\x=\dfrac{18}{0.05}\\\\x=360

Hence, they will charge same amount for 360 minutes of calls.

☰ Question (part 1 of 2) This is a two-part question, make sure you answer both parts: Flo Tilla is pedal boating on Lake Azui.
Naddik [55]
For this, we use the given info plus a bit of multiplying and subtraction

part 1)

we know that she's 25 y/m
so 5 minutes simply means 25 × 5
25 \times 5 = 125 \: yards

now we simply subtract this from 1000 (the original distance)
1000 - 125 = 875 \: yards

part 2)

the total time taken is even easier to find
all we have to do is divide 1000 by 25
1000 \div 25 = 40 \: minutes
