Jaida is shopping for new school shoes. She buys a pair of Nikes for $85, a pair of Adidas for $64 and a pair of flats for $30 less than the Adidas shoes. How much money did she spend in all?

We can solve this using algebra

lets n be Nike and a be Adidas

she buys 1 pair of n

1 pair of a

1 pair of a - 30

WE put this all together

n + a + a - 30 = x

x is the total cost of the shoes

Now all we need to do is substitute the prices into the equation

85 + 64 + 64 - 30 = x

X=183

She spent $183 in total

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
