Dylan and dusty plan to take weekly surfing lessons together. if the 2-hour lessons are $20 per person and they plan to spend $100 each on new surfboards, what is the maximum number of lessons the two can take if the total amount spent for lessons and surfboards is at most $480?

Each one can take 7 lessons.

Step-by-step explanation:

Dylan and Dusty plan to take weekly surfing lessons together.

They want to spend $100 each on new surfboards = $100 × 2

                                                                                     = $200

They want to spent total amount for lessons and surfboards is at most $480.

After spending on two new surfboards the money left with

= 480 - 200

= $280

The charges for 2-hours classes for surfing lessons = $20 per person

The charges for 1 hour classes for them = $20.00

With $280  they will be able to take maximum number of lessons

=

= 14 lessons

Each one can take 14/2 = 7  lessons.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
