Solve the word problem using SELFIE and the distributive property of multiplication. Word problems should be answered in a complete sentence. Alex is driving across the country. He needs to drive 8 hours a day for 15 days in order to get to his destination. So far, he has driven 52 hours. How many more hours of driving does Alex have?

68 hours

Step-by-step explanation:

Given

Required

Determine the time left

First, we need to determine the expected time for Alex's trip

The time left is calculated as thus:

Apply Distributive Property

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!

b. b < 1 might be the correct answer
