jacob decided to start saving for college. after 3 months, he had saved $174. his friend victoria was inspired to do the same. after 6 months, she had saved $360. if they are both saving money at a constant rate, how many more dollars per month does victoria save than jacob? $ per month
Answer
Explanation:
Step1: Calculate Jacob's monthly - saving rate
To find Jacob's monthly - saving rate, divide the total amount he saved by the number of months. Jacob saved $174 in 3 months. So his monthly - saving rate $r_J=\frac{174}{3}$. $r_J = 58$ dollars per month.
Step2: Calculate Victoria's monthly - saving rate
To find Victoria's monthly - saving rate, divide the total amount she saved by the number of months. Victoria saved $360 in 6 months. So her monthly - saving rate $r_V=\frac{360}{6}$. $r_V = 60$ dollars per month.
Step3: Find the difference in their monthly - saving rates
To find how much more Victoria saves per month than Jacob, subtract Jacob's monthly - saving rate from Victoria's monthly - saving rate. The difference $\Delta r=r_V - r_J$. $\Delta r=60 - 58=2$ dollars per month.
