Question

tonia and tricia spent the day at the mall. At the end of the day, the two added up their purchases and found that they spent a total of 107.50. Toni spent 10.00 more than tricia. Write an equation that can be used to find how much each girl spent

Answer 1

Let Tricia's total amount spent equal x, since the amount she spent determines Toni's.

Tricia = x

Toni spent Tricia's amount plus $10, so Toni spent = x + 10.

 

Add the two terms (x) and (x+10) and set equal to the total cost, 107.50

 

x + x + 10 = 107.50

Combine x terms

 

2x + 10 = 107.50

Subtract 10 from both sides.

 

2x = 97.50

Divide both sides by 2.

 

x = 48.75

 

Remember that x is the amount that Tricia spent. Tricia spent $48.75.

Toni spent $10 more, so Toni spent $58.75.
