Question

PLEASE SOLVE. Students are selling candy bars. They earn $0.50 for each one they sell. They want to earn at least $455. Write and solve an inequality to find the fewest candy bars they can sell and reach their goal.

Answer 1

So each candy bar is .50 and they want to reach 455.00

we see how many .50's can go into 455.00

we notice that .50 times 2=1
so if we multiply the 455  1's by 2 we get how many candy bars to sell or
910.00

Answer 2

Let's use C as a variable for the number of candy bars they sell.
0.50C=455

To get what C is you have to divide both sides of the equation by 0.50, or half.

Dividing by half is the same as multiplying by 2, so 455 times 2 is 910.

C=910.
