Can someone plz explain??? I don't get this?? Example 4:
Cloths Are Us and Ratcliffe's are having sales. At Clothes Are Us, a pair of sneakers is on sale for 40% off the regular price of $50. At Ratcliffe's the same brand of sneakers is discounted by 30% off the regular price of $40. Which store has the better sale price? Explain.
Find the sale price of the sneakers at each store.

CLOTHES ARE US
60% of $50=0.60*$50=$30

RATCLIFFE'S
70% of $40=0.7*$40=28

$28<$30

I don't get how they got the percents 60% and 70%

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

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.

the aswere is the one with all 8's and the second one is with the 10,8 and 6
