Question

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?

Answer 1

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
