Answer:
57.4g
Step-by-step explanation:
32.8g of sugar is needed to make 4 cakes. How much sugar is needed for 7 cakes?
From the above questions, we know that:
4 cakes = 32.8g
7 cakes = x g
Cross Multiply
4 × xg = 7 × 32.8g
x = 7 × 32.8g/4
x = 57.4 g
Therefore, 57.4g is needed for 7 cakes
F(3k)=3k +7 Equals 9k+7. So 9k+7 would be the Answer.
42x+18y
Is probably the correct answer
