rate of $5 per day. write an equation stating when the two will have the same amount of money.
now, solve the equation.

day 11

equation: 100-3d=20+5e

Step-by-step explanation:

do a table. 100-3: 20+5: 97-3:25+5 until you get to the same number. I think that's how you do it. I hope it helps.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

answer for #1 is c

answer for #2 is d
