Answer: it would take 3.1 months

Step-by-step explanation:

Let m represent the number of months that that it will take either of the runners to have the same amount of money in their accounts.

Let y represent the total amount that runner 1 saves for m months

Let z represent the total amount that runner 2 saves for m months

The first runner has $112 in savings, received a $45 gift from a friend, and will save $25 each month. This means that the total amount that he will save for m months would be

y = 112 + 45 + 25m

y = 157 + 25m

The second runner has $50 in savings and will save $60 each month. This means that the total amount that he will save for m months would be

z = 50 + 60m

To determine the number of months before the amount in the account of both runners becomes the same, we would equate y to z. It becomes

157 + 25m = 50 + 60m

157 - 50 = 60m - 25m

35m = 107

m = 107/35

m = 3.06

garik1379 [7]

Answer:(c)

Step-by-step explanation:

Given

The initial value of Adam's model is A_o=\$550

the value increases exponentially with the rate of r\%

Time period t=5\ years

Final amount A=\$736

Exponential growth is given by

\Rightarrow A=A_o(1+r)^t

Putting values

\Rightarrow 736=550(1+r)^5\\\\\Rightarrow (1+r)^5=1.338

\Rightarrow 1+r=1.05999\\\Rightarrow r=0.05999\ or\ 5.99\%\approx 6\%

Option (c) is correct
