Grace started her own landscaping business. She charges $6 an hour for mowing lawns and $11 per house pulling weeds. In Septembe

marshall27 [118]

Answer:

The total money made by Grace is $477.

Step-by-step explanation:

Given:

Charge per hour for mowing lawn = $6

Charge per hour for pulling weeds = $11

Number of hours for which lawns are mowed = 63 hours

Number of hours for which weeds are pulled = 9 hours

Now, total money made by Grace in September can be calculated by adding the total money gained in mowing lawns and pulling weeds.

Total money gained in mowing lawns is given as:

$C_m=\textrm{Number of hours of mowing}\times\textrm{Charge per hour}\\\\C_m=63\times 6=\$378$

Total money gained in pulling weeds is given as:

$C_w=\textrm{Number of hours of pulling weeds}\times\textrm{Charge per hour}\\\\C_w=9\times 11=\$99$

Now, total money made = $C_m+C_w=378+99=\$477$

Therefore, the total money made by Grace is $477.

Da Shari wants to rearrange the four sweaters, two coats, and five jackets that are in her closet. If she puts a sweater first a

algol13

Solution:

Fabric possessed by Da. Shari = 4 Sweaters + 2 Coats + 5 Jackets= 11 in all

Arrangement that Da Shari wants to arrange 4 Sweaters + 2 Coats + 5 Jackets is to put "a sweater first and a jacket last".

After putting a sweater first and jacket last , total fabric which needs to be arranged is (3 Sweaters + 2 Coats + 4 Jackets)=9 in all.

Total number of possible arrangement = (1 sweater) × [9 fabric=(3 Sweaters + 2 Coats + 4 Jackets) arrangement] × (1 Jackets)

= 1! × 9 ! × 1!

= 9 !

= 9 × 8 × 7× 6× 5× 4× 3×2×1

= 362,880 ways
