Creative Crafts

Creative Crafts has a $10 supply charge, which means that no matter how long we spend learning scrap booking, we'll always pay at least $10. This represents our y-intercept, which can be used in our equation. Creative Crafts also charge $15 per hour, which represents our slope. Using this information we can make an equation.

Scrapbooks Incorporated charges $20 per hour, which represents our slope. Since Scrapbooks Incorporated charges no down payment, the y intercept is at the origin, or 0. Using this information, we can make an equation.

To solve the system of equations, we can substitute the second equation into the first equation.

x equals 2, which means 2 hours. In the context of the problem that represents the number of hours it takes for the two classes to charge the same amount of money.

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.
