Mr graves’ fifth-grade class is selling packages of energy-saving light bulbs to raise money for a class trip. each package costs $32.the students need to raise $2,500.about how many packages of light bulbs must they sell?

79

Step-by-step explanation:

Ok so we have the amount they need at least which is 2500, now we have 32 which is how much each package is being sold for, and we have x which is the number of of packages being sold.

2500= 32x, now we divide both sides by 32 to isolate x. When you do that you get 78.125, but since you don't sell 1/8 of a package you sell 1 more. Therefore you sell at least 79 packages.

Hopefully this helped!

80

Step-by-step explanation:

2,500 divided by 32 = 78 R4

78 R4 rounded to the nearest ten is 80

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
