1 u + 312 |
(a)
After
Number of scones that Penelope had = 1 u
Number of scones that Mrs Yang had = 5 x 1 u = 5 u
Before
Number of scones that Penelope baked = 1 u
Number of scones that Mrs Yang baked = 1 u + 454
5 u = 1 u + 454 - 142
5 u - 1 u = 312
4 u = 312
1 u = 312 ÷ 4 = 78
Number of scones that Penelope baked
= 1 u
= 78
(b)
Number of scones that Mrs Yang baked
= 1 u + 454
= 78 + 454
= 532
Answer(s): (a) 78; (b) 532
