Lin’s family has completed 40% of a trip. They have traveled 24 miles. How far is the trip? (If you get stuck, draw a tape diagram) Then

Marco bought a doll for his little sister. The price on the tag was $35, but it was on sale for 80% off. How much did Marco pay for the doll?

1) 60 miles

2) 7 dollars

Step-by-step explanation:

1) Question 1

Let x be equal to the full distance of the trip

Divide both sides by 0.4

Therefore, the trip is 60 miles long.

2) Question 2

Let y be equal to the price that Marco paid for the doll.

We multiply 35 by 1-0.8 because the doll is 80% off, meaning he's paying for 20% of the original price

Therefore, Marco paid $7 for the doll.

I hope this helps!

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
