Answer 1

Do you have any idea

Answer 2

I think so

Answer 3

So we have $20 and we make $0.05 for each cup

And we need to reach $35.50 to buy a toy

What's our first step

Answer 4

20+ 0.05x ≥ 35.50

Answer 5

right?

Answer 6

We can also just use an equal sign, but that's fine too because we need at least $35.50

Answer 7

k

Answer 8

Do you know how to solve for x now

Answer 9

I think so

Answer 10

Go for it! Show your work and I'll make sure you're doing it right

Answer 11

20-020+0.05x= 35.50-20

Answer 12

so then we have to 0.05x= 15.50

Answer 13

then we do 0.05x/0.05 15.50/ 0.05

Answer 14

And for the finals sum she will have to sell 310 cups of lemonade in order to get enough money for her to buy her toy.
