Question

1. Mr. Holloway is a craftsman who makes custom guitars by hand. His last order was for 2 guitars, and it took him 8 weeks to make them. He receives an order to make 7 guitars.If he makes the guitars at the same rate, how long will it take Mr. Holloway to make the guitars?

a=28
b=7
c=4
d=35
2. Solve for x : 4 x - 7 = 49
a=12
b=56
c=14
d=28
3. Michael ordered a chicken parm sandwich for $8, Xavier and Daniel both got a meatball sub for $7.75, and Tony got a veal parm for $9. Tony just got paid so he said the meal was on him as long as his friends took care of the tip. If they left an 18% tip how much would each of Tony's friends pay if they split it evenly?
a=$32.50
b=$5.85
c=$38.35
d=$1.95
4. Simplify: 5 * (10 * 6 + 9) - 9
a=345
b=336
c=291
d=741

Answer 1

28 weeks

Explanation:

It takes Mr. Holloway 8 weeks to make 2 guitars. Write this as a rate.

8 weeks

2 guitars

Divide the numerator and denominator by 2 to find the unit rate.

8 weeks÷2

2 guitars÷2

=

4 weeks

1 guitar

It takes Mr. Halloway 4 weeks to make 1 guitar. You want to find how long it will take him to make 7 guitars. Write a proportion.

4 weeks

1 guitar

=

? weeks

7 guitars

Compare the denominators.

4 weeks

1guitar

=

? weeks

7guitars

To get from 1 to 7, multiply by 7. Multiply the numerator and denominator by 7 to find how long it will take Mr. Halloway to make 7 guitars.

1 guitar7

=

28weeks

7 guitars

It will take Mr. Halloway 28 weeks to make 7 guitars.

Answer 2

1) 28 weeks or A

2) 14 or c

Explanation:

1) 8/2= 4

4 multiplied by 7 = 28

answer is 28

2) 4x-7=49

add 7 to both sides

4x=49+7

4x=56

divide 56 by 4

56/4=12

answer is 12
