First box under the equation: 2064

Second box under the equation: 5160

Total: 7224

Answer back as a decimal: 0.07224

Step-by-step explanation:

Multiply out the numbers without the decimals to make it more simple. Because the original number has 5 numbers behind the decimal points, you would move it over 5 spaces to get 0.07224.

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!
