Question

Trey is taking his friends out to dinner to celebrate graduation. It will cost him $72 to reserve a table, and another $5 per guest. How many people can he invite if he can only spend up to $130?​

Answer 1

11 people

Explanation:

first, youd subtract the table reservation price from the max price.

130 - 72 = 58

then, since each person costs $5, you find the highest multiple of 5.

in this case, its 55, which has 11 groups of 5 in it.

to make sure:

you can then subtract 55 from 58 to make sure there isnt any extra 5's.

58 - 55 = 3.
