Brad wants to buy flowers for his friend with $45 the daisies are $1 each and roses are $2 each he buys 3 more daisies then roses how much did the roses cost

Represent the number of roses by x and that the number of daisies is x + 3. The cost of x roses is equal to 2x and the daisies cost 1 (x + 3). Hence, the total cost of the flowers may be expressed as 2x + x + 3. This value should be equal to $45.

2x + x + 3 = 45; x = 14

The roses cost 2x. Therefore, the answer is $28.
