Answer:
15
Step-by-step explanation:
Danny buys 4 pizzas and some pretzels for his baseball team.
The cost of each pizza is $8.99
Total cost of 4 pizza = 4 × 8.99
= $35.96
Let buy p numbers of pretzels whose cost $0.99 each.
Total cost for p pretzels = 0.99p
Total spend by Danny on pizzas and pretzels = $50.81
35.96 + 0.99p = 50.81
0.99p = 50.81 - 35.96
0.99p = 14.85
p = 15
Hence, Danny bought 15 pretzels for baseball team.
