7. Shamirah and her friends go to the pizza restaurant and buy 4 pizzas and 7 drinks which cost £17.05. James and his friends buy 3 pizzas and 5
drinks and pay £12.50. Calculate the price of one pizza and one drink.

pizza = £2.25

drink = £1.15

Step-by-step explanation:

Shamirah and friends= 4p+7d=£17.05

James and friends=3p+5d=£12.50

21p+35d=87.50

20p+35d=£85.25

subtract

p+0=2.25

add value to original

(4*2.25)+7d=17.05

9+7d=17.05

-9          -9

7d=8.05

d=1.15

values of p and d

p = £2.25

d = £1.15

its 4 because 2 times 2 is 4, if you double the number two you get four
