On a map with a scale 1: 100,000 the distance between two cities is 12cm. what would be the distance between these two cities on a different map with a scale 1: 300,000?

Part 1)

we have

the scale is

the distance on a map is

we know that

The scale is equal to the distance on a map divided by the real distance

Let

x------> distance on a map

y-------> real distance

S-------> scale

In this part we have

Find the value of y

Substitute the values

Convert to kilometers

Part 2)

In this part we have

Find the value of x

Substitute the values

Convert to centimeters

therefore

the answer is

The distance is

`1234567890-=/*-qwertyuiop[]asdfghjkl; '\\zxcvbnm,./+ /

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
