Given the tables represents the supplies needed to make two types of jewelry
Part A: we will write an expression to determine the cost of supplies to make 1 bracelet.
From the second table:
To make 1 bracelet we need 25 beads and 4 charms
From the first table:
The cost of one bead = $0.05, and the cost of charm = $0.45
So, the expression will be:
![25\mleft(0.05\mright)+4\mleft(0.45\mright)=3.05](https://img.qammunity.org/2023/formulas/mathematics/college/z2kxkcr2pjc4as1ycia3bi5j781xny7d18.png)
Part B: We will write an expression to determine the cost to make 2necklaces
Form the second table:
To make 1 necklace we need 48 beads and 1 charm
From the first table:
The cost of one bead = $0.05, and the cost of charm = $0.45
So, the expression will be as follows:
![2(48(0.05)+1(0.45))=5.7](https://img.qammunity.org/2023/formulas/mathematics/college/ndggpbi22e6k5r4qukm583gvw7c0odgwj4.png)
Part C: We will find the left money if she started with $40
So, first, we will find the total cost by adding the expressions of part A and part B
![25(0.05)+4(0.45)+2(48(0.05)+1(0.45))=3.05+5.7=8.75](https://img.qammunity.org/2023/formulas/mathematics/college/rzwqur1tpvfh9rwpn9s5z3ppagd6awg85w.png)
Second, subtract the total cost from $40
So, the money left =
![40-8.75=31.25](https://img.qammunity.org/2023/formulas/mathematics/college/8n5t0gyn3tkj53p772urpwypi4np5azivv.png)
So, the answer of part c: the money left = $31.25
