# Mary and Tina spent a total of $175 at the mall. Tina spent$10 more than twice as much as Mary. How much did tina spend?

I found $120 #### Explanation: Call the amount of money spent by Mary and Tina as $M$and $T$you get: $M + T = 175$$T = 10 + 2 M$substitute the second into the first: $M + 10 + 2 M = 175$solve for $M$: $M = \frac{165}{3} = 55
$T = 10 + 2 \cdot 55 = 120$ \$
