has $330 in her bank account and spending $20 per
Christmas gift.
Write an equation to represent the situations.
How many gifts do they need to buy so that they have
the same amount of money in their accounts?

Respuesta :

Answer:

12 gifts

Step-by-step explanation:

set the equation to 270-15x=330-20x

david: 12g=270

her: 20g=330

david buys 5 gifts he will have 210 dollars left in his account ( 12x5= 60 & 270 - 60 = 210)

if kristin buys 6 gifts she will have 210 dollars left  ( 20x6= 120 & 330-120= 210)
