Question

(a) The cost of 1 apple is a cent.
The cost of 1 pear is p cents.
The total cost of 7 apples and 9 pears is 354 cents.

(i) Write down an equation in terms of a and p.

(ii) The cost of 1 pear is 2 cents more than the cost of 1 apple.
Find the value of a and the value of p.

Answer 1

Step-by-step explanation:

One apple costs a cents, so 7 apples costs 7*a, or just 7a, cents

One pear costs p cents, so 9 pears costs 9p cents

Together, these add to 354 cents, the equation is 7a + 9p = 354

Answer 2

Answer:

Step-by-step explanation:

(i)   Equation in terms of a and p

    a*7+ p*9=354

(ii) value of a and p

  a*(7)+(a+2)*9=354

  solving the above equation for a

  we get value for a as 21

  p= 23
