Young Sally went Trick or Treating last Halloween, In her treat bag were 15 pieces of gum, 7 lollipops, 8 tootsie rolls, 6 candy

Vilka [71]

Answer:

A: 16.2% (if you need it rounded, it is 16%)

B: 43.2% (if you need it rounded it is 43%)

Step-by-step explanation:

We need to find the candy bar percentage rate so we divide the amount of candy bars, by the total about of treats collected.

15 + 7 + 8 + 6 + 1 = 37

Now we divide the cady bars by the total amount:

6/37 = 16.2%

Now we do the same thing again but this time with the apples and gum:

16/37 = 43.2%

You did it!

Have a great day!!

Please help me with this two questions

Annette [7]

Answer:

a.) 10 months

b.) Kool Karate

c.) Karate Klub

Step-by-step explanation:

Karate Klub : y=25x+200

Kool Karate : y=35x+100

A.) First, set the equations equal to each other then solve for x. $A.) 25x+200=35x+100\\\\$

take away 100 from both sides

$25x+100=35x$

take away 25x from both sides

$100=10x$

divide 10 from both sides so x can be by itself and equal to 1

$10=x$

This means that at 10 months, the cost is the same for both.

B.) Substitute 6 for x in both equations

Karate Klub : $y=25(6)+200\\y=350$

Kool Karate : $y=35(6)+100\\y=310$

The cost for Kool Karate is cheaper, so that is what he should join.

C.) Substitute 12 for x in both equations.

x=12 because there are 12 months in a year.

Karate Klub: $y= 25(12)+200\\y=500$

Kool Karate: $y=35(12)+100\\y=520$

The cost for Karate Klub is cheaper, so that is what he should join.
