write down an equation in terms of a and p.

Question

the cost of 1 apple is a cents.

the cost of 1 pear is p cents.

the total of 7 apples and 9 pears is 354 cents

 

Answer 1

 

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
