Dan started shopping with $100 he went to two stores and spend equal amount at both stores when he finished he had $24.24 left how did he spend at the first store

He spend $37.88 at the first store.

Step-by-step explanation:

Since we have given that

Total amount he started shopping with to two stores = $100

Amount he left with = $24.24

According to question, he spend equal amount at both stores.

Let the amount he spend at each store be 'x'.

So, our equation becomes,

Hence, he spend $37.88 at the first store.

-2.

Step-by-step explanation:

4x + 5y = -12

-23.4x + 3y = -16

23.4[4x + 5y = -12]

4[-23.4x + 3y = -16]

93.6x + 117y = -280.8

-93.6x + 12y = -64

129y = -344.8

y = -2.672868217

That is about -2.

Hope this helps!
