a. Haruto has tomato plants in his backyard. This year the plants grew 127 tomatoes. Birds had eaten 19 of the tomatoes. 23 tomatoes had been ruined by bugs. He picked the rest. How many tomatoes did Haruto pick?
Step-by-step Solution:
1.
Total tomatoes grown: 127
2.
Tomatoes eaten by birds: 19
3.
Tomatoes ruined by bugs: 23
We need to subtract both the eaten and ruined tomatoes from the total to find how many were left for Haruto to pick.
First, add the lost tomatoes:
> 19 (birds) + 23 (bugs) = 42 tomatoes lost
Now subtract from the total:
> 127 – 42 =
85
✔ Answer: Haruto picked 85 tomatoes.

b. Webster Elementary School has 124 first graders and 130 second graders. On Friday, 12 first graders and 9 second graders were absent. How many first and second graders were in school on Friday?
Step-by-step Solution:
1.
First graders present:
Total first graders – absent first graders
= 124 – 12 =
112
2.
Second graders present:
Total second graders – absent second graders
= 130 – 9 =
121
Now, add them together to get total students in school:
> 112 + 121 =
233
✔ Answer: 233 first and second graders were in school on Friday.

c. Cole and Bryon went to Video Game Land. Cole won 152 tickets. Bryon won 84 tickets. They want to put their tickets together to get a large toy monkey that costs 300 tickets. How many more tickets do they need?
Step-by-step Solution:
1.
Total tickets they have:
Cole’s tickets + Bryon’s tickets
= 152 + 84 =
236
2.
Tickets needed for the monkey: 300
3.
Additional tickets needed:
300 – 236 =
64
✔ Answer: They need 64 more tickets.

2.
Jake’s cookies: Twice as many as Clementine
= 2 × 72 =
