Johanna is planting tomatoes in the school garden this year. Tomato plants come in packs of six. She needs 80 plants in the garden and already has 28. How many packs of plants will she need? Homework Help ✎
For each pack Johanna will gain 6 more tomato plants, so multiply each pack by 6.
She already has 28 tomato plants and she needs 80.
If she has 28 plants, how many more does she need to have 80?
Divide this number by 6 and round up the nearest whole number of packs.
