Jennie makes quilts. She can make 7 quilts with 21 yards . How many yards to make 12 quilts

Answers

Answer 1

Answer: If she can make 7 quilts with 21 yards, then you know 21÷7=3, it takes 3 yards to make 1 quilt. To make 12 quilts, you would then multiply the amount needed for each quilt by the total number of quilts: 3 yards/quilt x 12 quilts= 36 yards needed to make 12 quilts.

trisha standford earns $300 a week plus a 15% commission only on sales she makes after her first $1,000 in sales if ms standfords sales for one week are $2,500 what is her gross pay for that week

Answers

Answer:

Her gross pay for that week=$525

Step-by-step explanation:

Step 1: Express the gross pay

The gross pay can be expressed as follows;

A=F+(R×T)

where;

A=the gross pay per week

F=fixed income per week

R=commission rate

T=total commission sales

In our case;

F=$300 a week

R=15%=15/100=0.15

T=(2,500-1,000)=$1,500

replacing;

A=300+(15% of 1,500)

A=300+(0.15×1,500)

A=300+225=525

A=$525

Her gross pay for that week=$525

Nina wants to download games for her video game console. Older games cost 100 points and new releases cost 200 points to use. The equation 100a+200b=4000, where a is the number of der games and b is the number of new releases, models the situation. How many older games can she download if she downloads 4 new games? 5 new games?

Answers

Replace b with 4: 100a+200(4)=4000. 100a+800=4000. Combine like terms: 100a=3,200. Get the unknown by itself: A=32. She can download 32 old games if she downloads 4 new ones. Same steps: 100a+200(5)=4000. 100a+1000=4000. 100a=3000. A=30. She can download 30 old games if she downloads 5 new ones. :)

Final answer:

If Nina downloads 4 new games, she can additionally download 16 older games. If she downloads 5 new games, she can download 15 older games.

Explanation:

The problem can be solved by substituting the number of new games into the equation and solving for 'a' which represents the number of older games.

For 4 new games, the equation becomes 100a+200*4=4000. Solving this, we get 'a' as 16. Hence, Nina can download 16 older games.

For 5 new games, the equation becomes 100a+200*5=4000. Solving this, we get 'a' as 15. Hence, Nina can download 15 older games when she downloads 5 new games.
