Question

Two runners are saving money to attend a marathon. The first runner has $112 in savings, received a $45 gift from a friend, and will save $25 each month. The second runner has $50 in savings and will save $60 each month.Which equation can be used to find m, the number of months it will take for both accounts to have the same amount of money?a.112 – 25m + 45 = 50 – 60mb.112 + 25 + 45m = 50m + 60c.112 + 25 – 45m = –50m + 60d.112 + 25m + 45 = 50 + 60m

Answer 1

Answer:

The right answer is: d.112 + 25m + 45 = 50 + 60m

Step-by-step explanation:

Let m be the number of months

He already has 112 in savings and got 45 from a friend so these will be constant values and as he will be saving $25 each month so

He already has $50 in saving and ill save 60 each month so

In order to find that when there accounts will have same amount, the expressions for both will be put equal

The value of m will give us the number of months after which the accounts of both runners will have same amount.

The right answer is: d.112 + 25m + 45 = 50 + 60m

Answer 2

The right answer is: d.112 + 25m + 45 = 50 + 60m

Step-by-step explanation:

Let m be the number of months

For First Runner:

He already has 112 in savings and got 45 from a friend so these will be constant values and as he will be saving $25 each month so

$112+45+25m$

For Second Runner:

He already has $50 in saving and ill save 60 each month so

$50+60m$

In order to find that when there accounts will have same amount, the expressions for both will be put equal

$112+45+25m=50+60m$

The value of m will give us the number of months after which the accounts of both runners will have same amount.

Hence,

The right answer is: d.112 + 25m + 45 = 50 + 60m
