Answer: 1a. $190
b. The total cost of making 20 bracelets.
c. $350
d. The total cost of making 100 bracelets.
e. $1150
f. The total cost of making 500 bracelets.
g. 150 bracelets
h. 425 bracelets
Step-by-step explanation:
1a. C(20)=150+2(20)
C(20)=150+40
C(20)=$190
b. The total cost of making 20 bracelets.
c. C(100)=150+2(100)
C(100)=150+200
C(100)=$350
d. The total cost of making 100 bracelets.
e. C(500)=150+2(500)
C(500)=150+1000
C(500)=$1150
f. The total cost of making 500 bracelets.
g. 450=150+2b
2b=300
b=150 bracelets
h. 1000=150+2b
2b=850
b=425 bracelets
She is totally a bad writer
Answer:
57 years old
Step-by-step explanation:
If two-thirds of a woman's age is 38, then:
(2/3)x = 38
Multiplying both sides by 3/2 to solve for x will give us her age:
3/2)(2/3)x = (3/2)*38
x =57
She is 57 years old.
Answer:10 more
Step-by-step explanation:
distributive property so 3*4+3*5 so 12 an 15 or 27. 3*4+5 is 12+5 so 17 27-17 is 10
