Question

Plzzz helpppp

Terry has 15 candles. She needs at least 100 candles. The candles she wants are sold in boxes of 8.


What is the least number of boxes of 8 candles that Terry needs to buy?

Answer 1

11 boxes of candles

Explanation:

first, set it up as an equation. let x stand for the amount of boxes she needs.

100=8x+15

next, subtract 15 from both sides of the equation.

100-15=8x+15-15

85=8x

then, you need to get x by itself. to do this, divide 8 from both sides of the equation.

85/8=8x/8

x=10.62, but you can't buy half a box, so you have to round up.

so, she needs to buy 11 boxes of candles.
