Answer: 6 toys; 11 books
Step-by-step explanation:
Let the number of books bought be represented by b.
Let the toys brought be represented by t.
b + t = 17
11b + 6t = 157
11 × (b + t = 17)
1 × (11b + 6t = 157)
11b + 11t = 187
11b + 6t = 157
Subtract from each other
5t = 30
t = 30/5 = 6
6 toys were bought
Since b + t = 17
b = 17 - 6 = 11
11 books were bought
The number of books and toys did she buy for $157 is 6 toys and 11 books.
Given that,
- Rose purchased a total of 17 books and toys for the Rupert Play School.
- Each book costs $11 and each toy costs $6.
- Here we assume book be b and toy be t.
Based on the above information, the calculation is as follows:
b + t = 17
b = 17 - t
11b + 6t = 157
11(17-t) + 6t = 157
187 - 11t + 6t = 157
30 = 5t
t = 6
And, b = 17 - 6
= 11
