A Pineapple And 4 Oranges Cost 8 40 The Pineapple Cost 5 90 More Than An Orange Find The Cost Of The Pineapple

I’m totally lost and any help would be greatly appreciated 

Solution

Kristi, don’t be lost.  This is a simultaneous equation problem because you have two unknowns.  You need two equations.  Here’s how: A pineapple and 4 oranges cost 8.40. The pineapple cost 5.90 more than an orange. Find the cost of the pineapple p + 4o = 8.40 p = o + 5.90 Substitute: o + 5.90 + 4o = 8.40 5o = 2.50 o = .50 p = 6.40
