If you invest money, after a certain period of time you’ll get interest. for example, if you invest $2,000 at 5% annual interest rate, in a year you will have $2,000∙0.05=$100 of annual simple interest in addition to the original amount. how much should you invest at 5% annual rate to have the annual interest of $150?

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

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!
