If you are single with no children, earn $36,000/year and set a savings goal of 5% per month, each month you should save

Each month you should save $ 150

Step-by-step explanation:

First, the earnings are given per year, so we need to transform $36000/year into dollars per month. So, using a rule of three as following, we obtain:

$ 36,000  ------------- 12 months

     X         -------------- 1 month

Solving for X, we get:

X = $ 3,000 /month

it means that earn $36,000/year is equivalent to earn $3,000/month

Now, we need to find the 5% of $3,000, this can be calculated making the following multiplication:

Then, each month you should save $150

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
