Answer:
7$
Step-by-step explanation:
1) 3x10=30 so 30 is how much money he needs
2)30-23=7 so 7 is how much he needs to borrow
Answer:
$7
Step-by-step explanation:
The reason is because three medium pepperoni pizzas cost $30, because you have to multiply $10x3 since each pizza cost $10. He already has $23 dollars in his pocket. You have to subtract his total value which is $23 from $30 to get $7.
