7 0

Answer:

35 2-point questions, and 15 5-point questions

Assume x 2-points question, so 50-x 5-points question

Total no of points: 2*x+5*(50-x)=145 points

2x+250-5x=145

-3x=-105

x=-105/-3=35 2-points questions

Remaining 50-35=15 5-points questions

ok so i really hope this helped and if it didn't then sorry

Ying Ying wants to buy some petunias.
Crazy boy [7]
2 petunias leave $6.50 on her wallet, and 8 leave $5.00. This means that 6 petunias cost $1.50, and that 1 petunia costs 25 cents.

.25 goes into 3.50 (the amount of money she has left in her wallet after buying 14 petunias) 14 times. 14 + 14 =28.

Ying Ying can buy 28 petunias at most.
