.Margaret is treating her best friend to a birthday dinner. Before ordering, Margaret wants to have an idea of the final bill. The order includes one appetizer for $6.50, two main courses for $15.75 each, two drinks for $2.25 each, and two desserts for $7.25 each. Round each amount up to the nearest whole dollar to find an overestimate of the total cost.

Your answer is 61.

Step-by-step explanation:

Simple enough! We simply round up each cost to the nearest whole dollar. $6.50 can be rounded to $7, $15.75 can be rounded up to $16, $2.25 can be rounded up to $3 (Note we're rounding up, in normal rounding we would round down to $2). Finally, $7.25 can be rounded up to $8.

Next comes simple algebra,

Therfore, your overestimate of the cost would be 61.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
