At the playground, 60% of the bike rack was filled. Thisis 30 bikes. How many total slots are there for bicycles?

Blizzard [7]

The most simplest way to explain this is by breaking down the 60%.

Think about it.

If 60% space = 30 bikes

then 30% space = 15 bikes

then 10% space must be 5 bikes.

So we now know for sure 60% space = 30 bikes.
And 10% space = 5 bikes.

Then we know remaining 40% space = 20 bikes.

So total space = 100% space, for 50 bikes.

Christopher has breakfast at a cafe and the cost of his meal is \$36.00$36.00dollar sign, 36, point, 00. Because of the service,

Leokris [45]

Answer:

His total bill including the tip = $39.6

Step-by-step explanation:

Christopher has breakfast at a cafe and the cost of his meal is $36.00

Because of the service, he wants to leave a 10% tip. This means that he would be paying more than the original cost of the meal. The cost of tip would be determined by multiplying the original cost of the meal by 10%. This becomes

Cost of tip = 10/100 × 36.00 =

0.1× 36.00= $3.6

His total bill including the tip would be sum of the cost of the original bill + cost of the tip. It becomes

36.00 + 3.6 = $39.6

3 A new club opens with 20 members, plus an unknown number of members from another club. The club allows only members to join on

Marina86 [1]

Step-by-step explanation:

let the unknown members be X

At first, the club had 20 + X members

After the first year,

2( 20+X)

The second year,

2( 20 +X/2) +40

The third year,

3[2(20+ X/2) +40]

Total number =

20+X + 2(20+X) + 2( 20 +X/2) +40 +3[2(20+ X/2) +40]

= 20+ X + 40+ 2X + 40 +2X/2 +40 +3[40+2X/2 +40]

= 20+40+X +2X +40+X+ 40 + 3[ 40+40+X]

= 60 +3X +80+X + 3[80+X]

= 140+4X + 240+3X

=380 + 7X

-380=7X

X = -54.3
