Complete question :

David wants to arrange the cars on his car lot. He wants to park the cars in

rows with the same number of each type of car in each row. What is the

greatest number of rows David can have?

Number of Cars

Sports Car-72

SUV-60

Sedans-48

Trucks-84

12 rows

Step-by-step explanation:

To obtain the greatest number of rows, take the highest common factor :

72 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72

60 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

48 : 1, 2, 3, 4, 6, 8, 12, 16, 24 48.

84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84

From the calculation above, the greatest number of rows David can have is 12

ian gone lie this got me confused

step-by-step explanation:

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!
