| Number |
1 u |
1 u + 5 |
|
| Value |
$2.30 |
$1.10 |
|
| Total value |
2.3 u |
1.1 u + 5.5 |
1.1 u + 5.5 |
Amount that Xylia paid for the cupcakes
= 1 u x 2.30
= 2.3 u
Amount that Xylia paid for cookies
= 1.1 x (1 u + 5)
= 1.1 u + 5.5
Total amount that Xylia paid
= 2.3 u + 1.1 u + 5.5
= 3.4 u + 5.5
3.4 u + 5.5 = 25.9
3.4 u = 25.9 - 5.5
3.4 u = 20.4
1 u = 20.4 ÷ 3.4 = 6
Number of cupcakes that Xylia bought
= 1 u
= 6
Answer(s): 6
