A machine is used to fill bags with 16 oz of sugar. After the bags are filled, another machine weighs them. If the bag weighs 1 oz more or less than the desired weight, the bag Is rejected. Which of the following best represents the equation that can be used to find the heaviest and lightest bag that the machine will approve?

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!

i those same problems in math and dont know how to do them
