Chandler bought 2 pounds of grapes for $3.99 per pound,
.5 pounds of apples for $1.75 per pound,
and 1.5 pounds of cherries for $4.90 per pound.
How much did Chandler spend altogether? Round your answer to the nearest penny, if necessary
The cost of 2 pounds of grapes is 2 * $3.99 = $<<2*3.99=7.98>>7.98.
The cost of .5 pounds of apples is .5 * $1.75 = $<<.5*1.75=.875>>.875.
The cost of 1.5 pounds of cherries is 1.5 * $4.90 = $<<1.5*4.9=7.35>>7.35.
Altogether, Chandler spent $7.98 + $0.875 + $7.35 = $16.20, rounded to the nearest penny. Answer: \boxed{16.20}.
