Answer:
126= 10p+4(p+7)
p=phones
Step-by-step explanation:
Since she sold 7 more accessories than phones, one part would be p+7. 10$ per phone, would be 10p, and $4 per accessory, would be 4(p+7). Add both expressions up.
Do you know how to solve simultaneous equation?
The time taken to get to the 4th can be obtained by dividing the distance given by the speed of the lift.
Distance, height from ground to 4th floor = 42 feets
Time taken to get to the 4th floor = t
Recall :
Time = Distance / speed
- We aren't given the speed of the lift ;
- Assume speed of lift is 7 ft/sec
The time taken to get to the 4th floor will be :
Therefore, to obtain the time taken, divide the distance or height of the 4th floor by the speed of the lift.
