Liam's bookstore sold 40 notebooks and 20 newspapers for a total of $130 dollar sign, 130.
A day later, the bookstore sold 8 notebooks and 4 newspapers at the same prices, for a total of $28 dollar sign, 28.
How much does a notebook and a newspaper cost at Liam's bookstore?
+36916 40 b + 20 n = 130 and
8 b + 4 n = 28 Multiply this equation by - 5 then add it to the top one to solve for b, notebooks
then substitute this value of 'b' into one of the equations to solve for 'n'
WAIT a minute ! THIS question makes no sense ! both of the quantities are reduced to 1/5th on the second day, but the amount is not decreased to 1/5th.....no answer .
