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**
