45 - 43.7 = $1.3

Step-by-step explanation:

a) Kohl’s is selling the speaker for $60.00. Mrs. House has a Friends and Family discount coupon for 25% off.

This means that the amount that he would have to pay would be the cost of the speaker - 25% of this cost and multiplied by 100. It becomes

60 - (25/100 × 60) = 60 - 15 = $45

So she would be paying $45 at Kohl

b) Target purchased the speaker for $38.00 and marked it up by 15% to sell in the store. The price that she will pay at Target would be the sum of the price at which Target purchased it + 15% of this price. It becomes

38 + (15/100 × 38) = 38 + 5.7 = 43.7

So she would be paying $43.7 at Target.

c) she would get the best deal at Target because it is cheaper there. She would be saving

45 - 43.7 = $1.3

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.
