The ratio of the number of girls to the number of boys was 4 to 5 if 1,530 students were present how many were girls and how many were boys?

680 girls and 850 boys

Step-by-step explanation:

the ratio of girls is 4/9

then we can find the number of girls (G) in the group of 1530 students using proportions:

4 / 9 = G / 1530

solving for G by multiplying both sides of the proportion by 1530, we get:

G = 4 * 1530 / 9 = 680

So there were:

680 girls and 1530 - 680 = 850 boys

The total cost for the car including tax is $27423.75

Step-by-step explanation:

The initial price of the car that you want is 25,750. If the sales tax rate is 6.5%, it means that the amount of sales tax would be

6.5/100 × 25750 = 0.065 × 25750 = 1673.75

The total cost for the car including tax would be the sum of the initial cost of the car and the amount of tax. It becomes

25750 + 1673.75 = $27423.75
