Below is a piece of a local pizza place menu where Jacob works.
1 answer:
1)
16.90 is about $17
$17 * 3 = 51
6.99 is about $7
7 * 4 = 28
28 + 51 = 79
This is not reasonable because it costs $79, which is more than $75.
7 * 3 = 21
21 + 51 = 72
The customer has enough for 3 supreme pizzas and 3 dessert pizzas.
2)
16.90 is about 17
5.99 is about 6
17 + 6 = 23
23 - 5 = 18
This is reasonable.
3)
14.85 is about 15
6.99 is about 7
15 + 7 = 22
22/100 = 0.22
0.22 * 22 = 4.84
This is reasonable.
4)
16.90 is about 17
14.85 is about 15
5.99 is about 6
6.99 is about 7
17 * 5 = 85
15 * 5 = 75
6 * 5 = 30
7 * 5 = 35
85 + 75 + 30 + 35 = 225
This is reasonable
5)
14.85 + 1.39(4) = 20
1.39 * 4 = 5.56
14.85 + 5.56 = 20.41
This is not reasonable because the total is more then $20.
