hey! there are many ways to solve this question, but here are two!
ONE: since Dora bought 48 cupcakes at $0.55 each (which is SO CHEAP i want these cupcakes :), the total amount she spent is 48*0.55, which is $26.40. the number of vanilla cupcakes are 3/8 of the number of total cupcakes, so the cost would be 3/8 of the total cost, or 3/8*26.40
TWO: since the vanilla cupcakes make up 3/8 of all the cupcakes, that means that there are 18 vanilla cupcakes (48*3/8). each cupcake costs $0.55, so to find the cost of 18 cupcakes, multiply 18 by 0.55
ANSWER: $9.90
hope this helped!
