Dave rented a limousine for his wife's birthday. the hourly rate is $70. they used the limousine for 5 hours, plus dave gave the driver a 10% tip. how much did he spend in total for the hourly charges plus tip?

i think that in total, he spent $385

Step-by-step explanation:

70 times 5, and then find 10% of that

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!
