4 0

Each medal is different and is handed out depending on the outcome of the race/order of the racers, so we're counting the number of permutations. 4 medals are given to 4 runners, so there are

nadezda [96]

You will have $310 in your account after 42 weeks.

Step-by-step explanation:

Graduation present = $100

Amount deposited per week = $5

Let, x be the number of weeks, therefore, the function is

f(x) = 100+5x Eqn 1

We will put f(x)=310 in Eqn 1 to find number of weeks.

$310=100+5x\\310-100=5x\\210=5x\\5x=210\\$

Dividing both sides by 5

$\frac{5x}{5}=\frac{210}{5}\\x=42$

You will have $310 in your account after 42 weeks.
