Charles wants to determine which car is the fastest. the actual speed of four cars is shown below:

car: a b c d
speed (in km/h): 60.34 60.32 60.33 60.35

if the speedometer can only measure to the nearest tenth of a second, which car will have a different measurement?

Car D

Step-by-step explanation:

Given :  

Car:                           A               B               C                  D

Speed (in km/h):    60.34        60.32       60.33           60.35

To find : which car have different measurement

Speedometer can only measure to the nearest tenth of a second

If the decimal part of the value is greater than or equal to 5 - digit is rounded off  

If the value is less than 5 - digit remain same

Now, we round of all the cars speed

Car A : 60.34 = 60.3

Car B : 60.32 = 60.3

Car C : 60.33 = 60.3

Car D : 60.35 = 60.4

Therefore, Car D is having different measurement.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

answer: i think one of the answer is $150 and $300?
