Step-by-step explanation:
C(500)=65×500+850
=32500+850
=33350
The required answer
Answer:
-6 & -2
Step-by-step explanation:
Check. Note that when you multiply two negative numbers, the answer will be positive:
-6 * -2 = 12
Note that when you add two negative numbers, if there is a positive & negative sign directly next to each other, you change it to a subtract sign:
-6 + (-2) = -6 - 2 = -8

First, you calculate the total amount of parts : 7 + 3 = 10
Next, divide the number by the total amount of parts : £500 ÷ 10 = £50
After that, you multiply the answer by the amount of parts needed on both sides of the ratio : £50 × 3 = £150 and £50 × 7 = £350
Finally put these answers back into the ratio : £150:£350
To check, make sure both sides of the ratio add up to the original number : £150 + £350 = £500
