$1.60 |
|
| Total value |
2.6 u |
1.6 u + 8 |
1.6 u + 8 |
Amount that Vanessa paid for the muffins
= 1 u x 2.60
= 2.6 u
Amount that Vanessa paid for cookies
= 1.6 x (1 u + 5)
= 1.6 u + 8
Total amount that Vanessa paid
= 2.6 u + 1.6 u + 8
= 4.2 u + 8
4.2 u + 8 = 24.8
4.2 u = 24.8 - 8
4.2 u = 16.8
1 u = 16.8 ÷ 4.2 = 4
Number of muffins that Vanessa bought
= 1 u
= 4
Answer(s): 4
