Kevin had 85 cupcakes for his birthday. He gave some of his cupcakes to 7 of his friends. Each friend received the same number of cupcakes, and then Kevin was left with 15 cupcakes. Write an equation can be used to find c, the number of cupcakes each friend received?
c = (85 - 15) ÷7
3 + 4 x 5
23
14 - c = 8
c = 6
Jill buys 9 bags of small beads. Each bag holds 125 beads. She gives 60 beads to her friend. How many beads, b, does she have left?
(9 x 125) - 60 = b
Rancho Sienna was collecting coats for the homeless. Brittany collected 125 jackets. Andrew collected 330 jackets. The fire department picked up 215 of the jackets collected to pass out before the first cold front. Write an equation to find, j, the total number of jackets the school has left over to donate.
j = (125 +330) - 215

Kate is baking cookies and the recipe says it will take 20 minutes to prepare the ingredients, and then 5 times as many minutes to bake them. Before Kate can get started, though, she must first melt the butter in the microwave for 2 minutes. What is the equation for how many minutes, m, it will take Kate to make the cookies?
20+(20x5)+2 = m

Joey has 264 candy canes to share with his 8 friends. He splits the candy canes evenly in 8 stockings. Then, he takes 2 candy canes out of each bowl and keeps them for himself. Write an equation to solve for c, the number of candy canes in each of Joey's friends stocking.
264 = (C − 2) × 8
8 x e = 48
e = 6
Dan as collected toys to donate to children for Christmas. He has collected 3000 toys. He will donate 250 toys to each school in his community. He has already donated 1200 to a local church. How many schools, s, can he donate to without going over the 3000 toys he collected?
s= (3000 - 1200) ÷ 250
