so we’re given $5 for the entry free, $2.50 per pound of blueberries, and $2 per pound of apples.
we clearly are looking for the equation that represent how Eva pays.
so the equation is 5(2.50b + 2a) because to calculate her total we need to multiply the $5 entry fee with the pounds per blueberries and apples. therefore giving us 5(2.50b + 2a).
