Kate earns $ 12.50 for each hour babysitting her baby sister. Her mom decided to give her a $ 4.50 per hour raise. How much more
Salsk061 [2.6K]

Answer:

$67.50

Step-by-step explanation:

<u>Method 1</u>

original rate = $12.50 per hour

therefore, money earned in 15 hours = 15 x 12.50 = $187.50

new rate = 12.50 + 4.50 = $17 per hour

therefore, money earned in 15 hours = 15 x 17 = $255.00

255 - 187.50 = $67.50

Therefore, Kate earns $67.50 more after the raise.

<u>Method 2</u>

As the raise is an additional $4.50 per hour, simply multiple 4.50 by 15 to calculate the extra money Kate earns:

4.5 x 15 = 67.50
