Answer:
10 chocolate donuts were bought.
Step-by-step explanation:
Given data:
Caspar bought 8 more jelly donuts than chocolate donuts.
He bought 5 times as many jelly donuts as chocolate donuts.
<em>In order for us to answer the we need to make equation from the statements given</em>
Let jelly donuts be denoted by X
Let chocolate donuts be denoted by Y
From this statement <em>'Caspar bought 8 more jelly donuts than chocolate donuts.'</em>
<em>X +8 = Y </em><em>(equation 1)</em>
From this statement 'He bought 5 times as many jelly donuts as chocolate donuts.'
5X = Y <em>(equation 2)</em>
<em>Solving simultaneous equations using the method of substitution.</em>
<em>Substituting equation 2 into equation 1</em>
X + 8 = 5X
8 = 5X - X
8 = 4X <em>(Making X the subject of formula by dividing both sides by 4)</em>
2 = X
<em>Substituting X into equation 2</em>
Y= 5 * 2
Y = 10
