Question

Isabella spends $4.87 on paintbrushes and paint. Paint costs $0.99. How many paintbrushes and how many units of paint does she buy? Please explain how you found your answer.

Answer 1

Isabella buys 3 paintbrushes and 1 unit of paint.

Step-by-step explanation:

To find the number of paintbrushes and units of paint Isabella buys, we need to subtract the cost of the paint from the total spent. Isabella spends $4.87 and the paint costs $0.99, so the cost of the paintbrushes is $4.87 - $0.99 = $3.88. Since each paintbrush costs the same amount, we can divide the total cost of the paintbrushes by the cost of a single paintbrush to find the number of paintbrushes. $3.88 / $0.99 = 3.92. Since you can't buy a fraction of a paintbrush, Isabella buys 3 paintbrushes. To find the number of units of paint, we can subtract the cost of the paintbrushes from the total spent. $4.87 - $3.88 = $0.99. Since each unit of paint costs the same amount, we can divide the total cost of the paint by the cost of a single unit of paint to find the number of units. $0.99 / $0.99 = 1. Isabella buys 1 unit of paint.
