Question

Arnold buys 3

Answer 1

Answer:

A) 3.6(1.85 + 2.30)

Step-by-step explanation:

Given that $3\frac{3}{5}$ pounds of grapes at $1.85/pound and $3\frac{3}{5}$ of red grapes at $2.30 per pound.

Given the mass of the different grapes is the same, the cost can be expressed as;

$C_g=3\frac{3}{5}\times \ 1.85\\\\C_r=3\frac{3}{5}\times\ 2.30\\\\C_t=C_g+C_r\\\\=3\frac{3}{5}\times \ 1.85+3\frac{3}{5}\times\ 2.30\\\\=3\frac{3}{5}( \ 1.85+\ 2.30)\\\\=3.6(\ 1.85+\ 2.30)$

Hence, the cost can be expressed as 3.6(1.85+2.30)
