The cost to rent a scooter is $15.50 per hour and the cost to rent a watercraft
is $22.80 per hour. use the expression 15.5s + 22.8w to determine how much it
would cost to rent a scooter for 3 hours and a watercraft for 1 hours.

Total cost = $69.3

Step-by-step explanation:

So we have cost of renting a scooter (s) = $15.5/hr

Cost of renting a watercraft (w) = $22.8/hr

The equation

Total cost = 15.5s + 22.8w

So, if the scooter is rented for 3 hours and the watercraft is rented for 1 hour this means:

SO it would cost totally $ 69.3

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!
