Answer:
Isabella bought
- 4 paintbrushes and
- 4 poster boards.
Step-by-step explanation:
COST OF ITEMS
Glass beads cost $0.28 per ounce
Paintbrush cost $0.95
Poster boards cost $0.75
Paint cost $0.99
How many ounces of glass beads bought at the cost of $1.68 =1.68/0.28 = 6 Ounces
She bought 6 Ounces of Glass beads
How many jars of paint she bought at $3.96 = 3.96/0.99 = 4 Jars
She bought 4 jars of paint
Money spent so far = 14 – (1.68 + 3.96) = $8.36
Cost of 1 paintbrush plus cost of 1 poster board =0.95 + 0.75 = $1.7
The number of paintbrushes and poster boards that can be bought with the cash left is =8.36/1.7 = 4.92, so we can buy approximately 4 each of paintbrush and poster board, which is more than 3 as required.
I will suggest she buy 4 paintbrushes and 4 poster boards.
4 paintbrushes will cost 4*0.95 =$3.8
4 poster boards will cost 4*0.75 = $3
Total amount spent for all four items= (1.68 + 3.96) + (3.8 + 3) = $12.44
This shows that the total amount spent ($12.44) is less that $14
