Petra is making necklaces to sell at a craft fair. the hardware for each necklace cost $3.75, and each bead cost $0.50. the number of beads petra needs depends on the the design she chooses. which expression gives the total cost to make 30 necklaces with b beads?

Let

h> number of hardware

b> number of beads

T> total cost for make necklaces

we know that

the total cost for one necklaces is equal to

T=3.75*h+0.50*b> h=1

T=3.75+0.50*b

so

the total cost for 30 necklaces is equal to

h=30

T=3.75*30+0.50*b> T=112.5+0.50*b

therefore

the answer is

The expression is equal to

T=112.5+0.50*b

Let

h> number of hardware

b> number of beads

T> total cost for make necklaces

we know that

the total cost for one necklaces is equal to

T=3.75*h+0.50*b> h=1

T=3.75+0.50*b

so

the total cost for 30 necklaces is equal to

h=30

T=3.75*30+0.50*b> T=112.5+0.50*b

therefore

the answer is

The expression is equal to

T=112.5+0.50*b

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
