Ericka is selling more baked goods. This time she has cupcakes for $1.50 each and brownies for $0.80
each. She makes a total of $30 and sold 15
brownies. Write and solve an equation to determine
how many cupcakes she sold.

12

Step-by-step explanation:

to find how much she made off of brownies, use this equation

15×.8=$12

then, to find how much she made off of cupcakes, subtract the amount she made off of brownies from the total price

$30 - $12 = $18

lastly, to find how many cupcakes could be bought with $18, divide 1.5 from 18

18 ÷ 1.5 = 12

so 13 cupcakea

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

50- 250 is correct i did that one too
