Did you figure it out?

Solution:  Bailey’s sales are equal to Carlos’s plus 21: B = C + 21. Carlos’s sales are equal to 2.5 times Devon’s: C = 2.5D. Devon’s sales are equal to Emma’s: D = E. Emma’s sales are equal to a quarter of Fran’s sales: E = 0.25F. Fran’s sales are equal to Ginny’s sales minus 1: G – 1.

 
 
 
 
 
 
 
 

 

 

 

 

 

 

Did you figure it out?

Solution:  Each week, Alice gets $20.00 and spends $15.00. So, she can save $20.00 – $15.00 = $5.00 per week. She needs $45.00 to buy the video game, so she can save up that amount in $45.00 ÷ $5.00 per week = 9 weeks.
